[0001] The present disclosure generally relates to air dispersion nozzles, aircraft comprising air dispersion nozzles, and / or methods of using air dispersion nozzles.

Background Art

[0002] Dispersion nozzles can control, direct, and / or regulate the flow of a fluid such as air and can be utilized in a variety of applications. As an example, an air dispersion nozzle can be utilized to form and / or define an air curtain to enable and / or facilitate, for example, different environmental controls on each side of the air curtain. As another example, an air dispersion nozzle can be utilized to regulate the airflow within an aircraft. In a specific example, an air dispersion nozzle can be utilized to form and / or define an air curtain within the cockpit of an aircraft to enable and / or facilitate, for example, separate environmental controls in the pilot seating area and the co-pilot seating area of the aircraft. Conventional air dispersion nozzles are relatively complex and utilize a significant number of parts that are manufactured separately and then assembled, and / or are relatively expensive. Accordingly, there is a need for an improved air dispersion nozzle, an aircraft comprising an improved air dispersion nozzle, and / or an improved method for using an improved air dispersion nozzle.

Summary of the Invention

[0003] This specification discloses an air dispersion nozzle, an aircraft equipped with an air dispersion nozzle, and a method of utilizing an air dispersion nozzle. The air dispersion nozzle includes an extension inlet chamber, an extension outlet chamber, and an extension slot extending between the extension inlet chamber and the extension outlet chamber, which fluidly interconnects the extension inlet chamber and the extension outlet chamber. The air dispersion nozzle also includes an inlet chamber extending from an inlet port to the extension inlet chamber. The inlet port is connected to the inlet chamber and configured to receive a flow of inlet fluid along the inlet flow axis. The air dispersion nozzle further includes a power fluid inlet port extending into the extension inlet chamber and configured to receive a flow of power fluid along the power flow axis. The air dispersion nozzle also includes a sensor support extending into the inlet chamber. The air dispersion nozzle further includes an extension outlet port extending from the extension outlet chamber. The extension outlet port is configured to discharge an outlet fluid flow, which includes both the power fluid flow and the inlet fluid flow, along the outlet flow axis.

The method also includes redirecting the flow of the driving fluid within the extension inlet chamber to generate a flow of slot fluid that flows through an extension slot and into an extension outlet chamber. The method further includes generating pairs of counter-rotating vortices in the flow of slot fluid within the extension outlet chamber. The method also includes discharging an outlet fluid flow from the extension outlet port along the direction of the outlet flow. [Brief explanation of the drawing]

[0006] Figures 1 to 10 provide exemplary and non-limiting examples of the air dispersion nozzle 100, aircraft 10, and / or method relating to the present disclosure. Similar, or at least substantially similar, elements are numbered similarly in each of Figures 1 to 10, and these elements may not be described in detail when referring to each of Figures 1 to 10 herein. Similarly, not all elements are numbered in each of Figures 1 to 10, but reference numbers associated with such elements may be used consistently herein. Elements, components, and / or features described herein with reference to one or more of Figures 1 to 10 may be included in and / or utilized in any of Figures 1 to 10 without departing from the scope of the present disclosure.

[0007] Generally, elements that are likely to be included in a given (i.e., a particular) embodiment are shown with solid lines, and elements that are optional for a given embodiment are shown with dashed lines. However, elements shown with solid lines are not necessarily essential for all embodiments, and elements shown with solid lines may be omitted from a particular embodiment without departing from the scope of this disclosure.

[0008] Figure 1 is a schematic diagram of an example of an aircraft 10 that may and / or utilize an air dispersion nozzle 100 according to the present disclosure. The aircraft 10 may also include an air intake conduit 30 which may be configured to supply a flow of driving fluid 70 to the air dispersion nozzle 100. The air dispersion nozzle 100 according to the present disclosure may be configured in any suitable way to control, direct, and / or regulate the flow of fluid or air within or inside the aircraft 10. Examples of air dispersion nozzles 100 are disclosed herein.

[0009] In some examples, the air dispersion nozzle 100 may be located inside the cockpit 20 of the aircraft 10. In some such examples, the air dispersion nozzle 100 may be configured to generate an outlet fluid flow 90 which can function as an air curtain 98. In some such examples, the air curtain 98 may flow between the pilot seating area 12 and the co-pilot seating area 14 of the aircraft 10 to allow, facilitate, and / or enable separate environmental controls between the pilot seating area and the co-pilot seating area. In other words, the air curtain 98 can restrict the airflow between the pilot seating area 12 and the co-pilot seating area 14, thereby enabling separate control of the pilot's environmental control 13 and the co-pilot's environmental control 15, for example, the pilot temperature in the pilot seating area 12 may be maintained differently from and / or separately from the co-pilot temperature in the co-pilot seating area 14.

[0010] In some cases, the air curtain 98 can reduce the possibility of cross-contamination between the pilot seating area 12 and the co-pilot seating area 14. In other words, the air curtain 98 can carry out airborne contaminants, such as particulate matter, bacteria, and / or viruses, thereby reducing the flow of airborne contaminants between the pilot seating area 12 and the co-pilot seating area 14.

[0011] The air dispersion nozzle 100 may include a sensor 282 which may be configured to detect one or more characteristics of the air in the vicinity of and / or within the air dispersion nozzle 100. In some such examples, the aircraft 10 may further include an environmental control system 40 which can communicate with the sensor 282. In some such examples, the environmental control system 40 may be configured to control the flow rate of the driving fluid flow 70 based at least in part on sensor readings from the sensor 282.

[0012] Figure 2 is a schematic diagram of an example of the air dispersion nozzle 100 according to the present disclosure. Figure 3 is a somewhat schematic side view of the air dispersion nozzle 100 according to the present disclosure, and Figures 4 to 9 provide additional diagrams of the air dispersion nozzle 100 of Figure 3. More specifically, Figure 4 is a bottom view of the air dispersion nozzle of Figure 3, Figure 5 is a view of the left end of the air dispersion nozzle of Figure 3, Figure 6 is a view of the right end of the air dispersion nozzle of Figure 3, Figure 7 is a cross-sectional view of the air dispersion nozzle of Figure 3 cut along line 7-7 of Figure 3, Figure 8 is a cross-sectional view of the air dispersion nozzle of Figure 3 cut along line 8-8 of Figure 3, Figure 9 is a cross-sectional view of the air dispersion nozzle of Figure 3 cut along line 9-9 of Figure 5, and Figure 10 is a cross-sectional view of the air dispersion nozzle of Figure 3 cut along line 10-10 of Figure 5.

[0013] The air dispersion nozzles 100 in Figures 2 to 10 may include and / or be more detailed diagrams of the air dispersion nozzle 100 in Figure 1. Accordingly, the structure, function, and / or features of the air dispersion nozzles 100 in Figures 2 to 10 may be included in and / or used with the aircraft 10 in Figure 1 and / or the air dispersion nozzles 100 of the aircraft 10 without departing from the scope of this disclosure. Similarly, the structure, function, components, and / or features of the aircraft 10 in Figure 1 may be used with the air dispersion nozzles 100 in Figures 2 to 10 without departing from the scope of this disclosure.

[0014] As shown in Figure 2 and collectively in Figures 3 to 10, the air dispersion nozzle 100 comprises an extension inlet chamber 150 and an extension outlet chamber 170. The extension inlet chamber 150 extends along the extension inlet chamber length 152, as shown in Figure 2, and the extension outlet chamber 170, or also the extension outlet chamber 170, extends at least partially along the extension inlet chamber length. The air dispersion nozzle 100 also comprises an extension slot 190, which is also referred to herein as and / or may be a tapered extension slot 190. The extension slot 190 extends between the extension inlet chamber 150 and the extension outlet chamber 170, and fluidly interconnects the extension inlet chamber 150 and the extension outlet chamber 170.

[0015] The air dispersion nozzle 100 further includes a driving fluid inlet port 220 extending into an extension inlet chamber 150 and an extension outlet port 230 extending from an extension outlet chamber 170. The driving fluid inlet port 220 is configured to receive a driving fluid flow 70 along the driving fluid axis 72 and / or in the driving fluid direction (as indicated by the arrows of the driving fluid flow 70).

[0016] The air dispersion nozzle 100 also includes an inlet chamber 260. The inlet chamber 260 extends from the inlet port 270 to the extension inlet chamber 150. The inlet port 270 is connected to the inlet chamber 260 and is configured to receive an inlet fluid flow 76 along the inlet flow axis 78. Additionally or alternatively, the inlet port 270 may be configured to receive an inlet fluid flow 76 in and / or along the inlet flow direction (as indicated by the arrows in the inlet fluid flow 76), the inlet flow direction may be oriented at a certain inlet flow inclination angle 94 with respect to the driving flow axis 72.

[0017] The extension outlet port 230 is configured to discharge the outlet fluid flow 90 along the outlet flow axis 92 and / or in the outlet flow direction (as indicated by the arrows for the outlet fluid flow 90). The outlet flow axis 92 is positioned at a certain outlet flow inclination angle 96 with respect to the driving flow axis 72. In other words, the driving flow direction can be said herein to be at a certain outlet flow inclination angle 96 with respect to the outlet flow direction. The outlet fluid flow 90 includes the driving fluid flow 70 and the inlet fluid flow 76.

[0018] The air dispersion nozzle 100 further includes a sensor support 280. The sensor support 280 extends into and / or opens into the intake chamber 260 and may be configured to house, fix, and / or hold a sensor 282. The sensor 282 may be configured to measure one or more characteristics of the intake fluid flow 76, as described in more detail herein.

[0019] While the air dispersion nozzle 100 and / or the aircraft 10 equipped with the air dispersion nozzle 100 is operating, the flow 70 of the motive fluid can be supplied to the elongated inlet chamber 150 through the motive fluid inlet port 220 in the motive flow direction and / or along the motive flow axis 72. This can include supplying the flow 70 of the motive fluid through the air supply conduit 30 of FIG. 1. The flow 70 of the motive fluid can be redirected within the elongated inlet chamber 150 to generate the flow 206 of the slot fluid, and the flow 206 of the slot fluid flows past the elongated slot 190 and / or into the elongated outlet chamber 170. Within the elongated outlet chamber 170, a pair 80 of counter-rotating vortices can be generated from or within the flow 206 of the slot fluid. The flow 90 of the outlet fluid that can be generated from the counter-rotating vortices 80 can then be discharged from the elongated outlet port 230 along the outlet flow axis 92 and / or in the outlet flow direction.

[0020] By generating the counter-rotating vortices 80, the uniformity can be improved, the linearity can be improved, and / or the laminarity of the flow 90 of the outlet fluid can be improved. Stated another way, the air dispersion nozzle 100 can discharge a linear flow 90 of the outlet fluid and / or a laminar flow 90 of the outlet fluid. Such a configuration can create a flow 90 of the outlet fluid suitable for a particular application, such as an air curtain 98, which is described in more detail herein.

[0021] By supplying the flow 70 of the motive fluid to the extension inlet chamber 150 via the motive fluid inlet port 220, for example, via the Venturi effect, a suction force can also be generated within the suction inlet chamber 260. In other words, the air dispersion nozzle 100 according to the present disclosure can function as a discharge pump, a Venturi pump, and / or an exhaust pump, and can be referred to herein as a discharge pump, a Venturi pump, and / or an exhaust pump, and / or can be made into a discharge pump, a Venturi pump, and / or an exhaust pump, where the flow 70 of the motive fluid provides a driving force for the flow 76 of the suction inlet fluid to flow into the exhaust pump. The exhaust pump can mix the flow 70 of the motive fluid and the flow 76 of the suction inlet fluid within the air dispersion nozzle 100, for example, within the extension inlet chamber 150 and / or within the extension outlet chamber 170, and the combination of the flow 70 of the motive fluid and the flow 76 of the suction inlet fluid can be discharged from the exhaust pump as the flow 90 of the outlet fluid.

[0022] Based on the above, the air dispersion nozzle 100 can be said to be configured in this specification, for example, to redirect the flow 70 of the motive fluid from the motive fluid flow direction to the outlet fluid flow direction to generate and / or produce the flow 90 of the outlet fluid, and further, to redirect the flow 76 of the suction inlet fluid from the suction inlet fluid flow direction to the outlet fluid flow direction. The above redirection can make the flow of the outlet fluid laminar so that the flow 90 of the outlet fluid is uniform or at least substantially uniform along the outlet port length 232 of the extension outlet port 230, and / or so that the flow of the outlet fluid is directed at least substantially uniformly in the outlet fluid flow direction. Additionally or alternatively, the above redirection can be such that the outlet fluid flow direction is oriented at an outlet fluid inclination angle with respect to the motive fluid flow direction.

[0023] In accordance with this disclosure, by including an intake port 270, an intake chamber 260, and / or a sensor support 280 within the air dispersion nozzle 100, several advantages may be provided compared to a conventional air dispersion nozzle that does not include an intake port 270, an intake chamber 260, and / or a sensor support 280. As an example, as described above, a sensor 282 which may be located within the sensor support 280 may be configured to measure one or more characteristics of the intake fluid flow 76, for example, the temperature, pressure, and / or water content of the intake fluid flow. The environmental control system 40 in Figure 1 may receive one or more characteristics of the intake fluid flow 76 and / or use this information to control one or more aspects of the environment inside the aircraft 10 11. In a specific example, the sensor 282 may measure the temperature of the intake fluid flow 76, and the flow rate of the driving fluid flow 70 may be controlled, regulated, and / or adjusted based at least in part on the temperature of the intake fluid flow. This configuration enables and / or facilitates precise temperature control of the cabin 11 without requiring additional and / or other sensors within the cabin 11.

[0024] The driving fluid axis 72 may have and / or be defined in any suitable orientation or relative orientation. For example, the driving fluid axis 72 may be perpendicular to, or at least substantially perpendicular to, the cross section, transverse surface, and / or surface of the driving fluid inlet port 220 over the driving fluid inlet opening 226 of the driving fluid inlet port 220. As another example, the driving fluid axis 72 may be parallel to, or at least substantially parallel to, the longitudinal axis 154 of the extension inlet chamber 150, as shown in Figure 2.

[0025] The outlet flow axis 92 may have and / or be defined in any suitable orientation or relative orientation. For example, the outlet flow axis 92 may be perpendicular to, or at least substantially perpendicular to, the cross section, transverse surface, and / or surface extending over the outlet opening 236 of the extension outlet port 230. As another example, the outlet flow axis 92 may be perpendicular to, or at least substantially perpendicular to, the longitudinal axis 234 of the outlet port 230.

[0026] The intake flow axis 78 may have and / or be defined any suitable orientation or relative orientation. For example, the intake flow axis 78 may be perpendicular to and / or at least substantially perpendicular to the intake port 270 and / or the cross section, transverse surface, and / or surface of the intake port 270 over the intake opening 272. As another example, the intake flow axis 78 may be parallel to and / or at least substantially parallel to the longitudinal axis 266 of the intake chamber 260.

[0027] The intake flow inclination angle 94 and / or outlet flow inclination angle 96, which may be collectively referred to as angles 94 / 96 in this specification, include and / or may be any suitable angle between the driving flow axis 72 and the intake flow axis 78, or between the driving flow axis 72 and the outlet flow axis 92. For example, angles 94 / 96 may be at least 45 degrees, at least 50 degrees, at least 55 degrees, at least 60 degrees, at least 65 degrees, at least 70 degrees, at least 75 degrees, at least 80 degrees, at least 85 degrees, at least 90 degrees, up to 135 degrees, up to 130 degrees, up to 125 degrees, up to 120 degrees, up to 115 degrees, up to 110 degrees, up to 105 degrees, up to 100 degrees, up to 95 degrees, and / or up to 90 degrees. In specific examples, angles 94 / 96 may be equal to or at least substantially equal to 90 degrees.

[0028] In other specific examples, the intake flow axis 78 and the outlet flow axis 92 may be parallel to each other or at least substantially parallel. Additionally or alternatively, the intake flow inclination angle 94 may be within a threshold angle difference with respect to the outlet flow inclination angle 96. Examples of threshold angle differences include an angle difference of up to 1 degree, at least 2.5 degrees, at least 5 degrees, at least 10 degrees, at least 15 degrees, up to 30 degrees, up to 25 degrees, up to 20 degrees, up to 15 degrees, up to 10 degrees, and / or up to 5 degrees.

[0029] The driving fluid inlet port 220 may have and / or be defined any suitable shape, configuration, and / or structure. For example, the driving fluid inlet port 220 may include and / or be circular, at least partially circular, and / or at least substantially circular driving fluid inlet port 220. As another example, the driving fluid inlet port 220 may be shaped, dimensional, and / or oriented to direct the driving fluid flow 70 along the longitudinal axis 154 of the extension inlet chamber, or at least substantially along the longitudinal axis 154 of the extension inlet chamber. As yet another example, the cross section, transverse section, and / or driving fluid inlet opening 226 of the driving fluid inlet port 220 may be perpendicular to or at least substantially perpendicular to the longitudinal axis 154 of the extension inlet chamber. This configuration can improve the uniformity of the flow 70 of the driving fluid into and / or within the extension inlet chamber 150.

[0030] In some examples, as shown by dashed lines in Figure 2 and by solid lines in Figures 5 and 10, the air dispersion nozzle 100 and / or its driving fluid inlet port 220 may include and / or be associated with a driving fluid acceleration structure 290. The driving fluid acceleration structure 290 may be adapted, configured, dimensioned, and / or molded to accelerate or increase the velocity of the driving fluid flow 70 when the driving fluid flow exits the driving fluid inlet port 220 and / or enters the extension inlet chamber 150, when present. Examples of the driving fluid acceleration structure 290 include a region with a reduced cross-sectional area, at least a partially tapered region, a venturi, an orifice, and / or multiple orifices. In a specific example, as shown in Figure 5, the driving fluid acceleration structure 290 includes a venturi with four orifices 292. In some examples, the driving fluid acceleration structure 290 may be configured to accelerate the driving fluid flow 70 to bring about a target or desired inlet flow rate for the inlet fluid flow 76, or to accelerate it by an amount sufficient to bring about a target or desired inlet flow rate for the inlet fluid flow 76.

[0031] The extension outlet port 230 may have and / or be defined in any suitable shape, configuration, and / or structure. For example, the extension outlet port 230 may include and / or be a rectangular extension outlet port 230, at least substantially rectangular extension outlet port 230, and / or a rectangular extension outlet port 230 with rounded corners. In some examples, the longitudinal axis 234 of the outlet port may be parallel to or at least substantially parallel to the longitudinal axis 174 of the outlet chamber 170 of the extension outlet chamber 170.

[0032] As described above, the extension slot 190 can be tapered. Such a configuration can improve the uniformity of the flow or flow rate of the slot fluid flow 206 by, for example, improving the uniformity of the flow passing through the extension slot and / or the flow along the slot length 192 of the extension slot 190.

[0033] The extension slot 190 has and / or can have any suitable shape, configuration, and / or structure that tapers along the slot length 192 of the extension slot 190, extends between the extension inlet chamber 150 and the extension outlet chamber 170, and / or fluidly interconnects the extension inlet chamber 150 and the extension outlet chamber 170. In some examples, the extension slot 190 may extend between a first slot end 196 and a second slot end 200 or may extend continuously. In some examples, as shown in Figure 2, the extension slot 190 may include a plurality of slot sections 204. In such a configuration, each slot section of the plurality of slot sections can fluidly interconnect a given region of the extension inlet chamber 150 with a corresponding region of the extension outlet chamber 170.

[0034] The extension slot 190 can taper in any suitable form. For example, as perhaps best shown in Figure 4, the extension slot 190 can have a first slot width 198 defined at a first slot end 196 and a second slot width 202 defined at a second slot end 200. The second slot width 202 may be different from the first slot width 198, and both the first and second slot widths 198 and 202 may be measured in a direction perpendicular to, or at least substantially perpendicular to, the elongated axis or slot length 192 of the extension slot 190. Additionally or alternatively, the first slot width 198 and / or the second slot width 202 may be measured in a direction perpendicular to, or at least substantially perpendicular to, the flow of the slot fluid flow 206 flowing through the extension slot 190.

[0035] In some examples, as shown in the figure, the first slot end 196 may be located relatively close to the driving fluid inlet port 220, and / or the second slot end 200 may be located relatively far from the driving fluid inlet port 220. In some examples, the first slot width 198 may be greater than the second slot width 202. In some examples, the extension slot 190 may taper from the first slot width 198 to the second slot width 202 and / or between the first slot width 198 and the second slot width 202, tapering monotonically, tapering linearly, and / or tapering in an arc shape.

[0036] It falls within the scope of this disclosure that the first slot width 198 differs from the second slot width 202 by any appropriate amount and / or ratio. For example, the ratio of the first slot width 198 to the second slot width 202 may be at least 1.1, at least 1.2, at least 1.3, at least 1.4, at least 1.5, at least 1.6, at least 1.7, at least 1.8, at least 1.9, at least 2.0, up to 4.0, up to 3.8, up to 3.6, up to 3.4, up to 3.2, up to 3.0, up to 2.9, up to 2.8, up to 2.7, up to 2.6, up to 2.5, up to 2.4, up to 2.3, up to 2.2, up to 2.1, up to 2.0, up to 1.9, up to 1.8, up to 1.7, up to 1.6, and / or up to 1.5.

[0037] Examples of the first slot width 198 include widths of at least 1.5 mm, at least 1.6 mm, at least 1.7 mm, at least 1.8 mm, at least 1.9 mm, at least 2 mm, at least 2.1 mm, at least 2.2 mm, at least 2.3 mm, at least 2.4 mm, up to 3 mm, up to 2.9 mm, up to 2.8 mm, up to 2.7 mm, up to 2.6 mm, up to 2.5 mm, up to 2.4 mm, up to 2.3 mm, up to 2.2 mm, up to 2.1 mm, and / or up to 2 mm. Examples of the second slot width 202 include widths of at least 0.5 mm, at least 0.6 mm, at least 0.7 mm, at least 0.8 mm, at least 0.9 mm, at least 1 mm, at least 1.1 mm, at least 1.2 mm, at least 1.3 mm, at least 1.4 mm, up to 2 mm, up to 1.9 mm, up to 1.8 mm, up to 1.7 mm, up to 1.6 mm, up to 1.5 mm, up to 1.4 mm, up to 1.3 mm, up to 1.2 mm, up to 1.1 mm, and / or up to 1 mm.

[0038] The air dispersion nozzle 100 and / or its components may have and / or be defined to have any suitable dimensions and / or dimensions such that they enable and / or facilitate the operation and / or use of the air dispersion nozzle in the installation of a target, for example, within the aircraft 10 in Figure 1, and / or in any suitable manner, and in some examples the air dispersion nozzle 100 may be used in environments where space is relatively limited, such as the aircraft 10.

[0039] In some examples, the extension inlet chamber 150 may have and / or be defined with an extension inlet chamber length 152, as shown in Figure 2. In some examples, the extension inlet chamber length 152 may be the maximum dimension of the extension inlet chamber 150, which can be measured along the longitudinal axis 154 of the extension inlet chamber and / or can be measured along the longitudinal axis of the extension inlet chamber. Additionally or alternatively, the extension outlet chamber 170 may have and / or be defined with an outlet chamber length 172, similarly shown in Figure 2. In some examples, the outlet chamber length 172 may be the maximum dimension of the extension outlet chamber 170, which can be measured along the longitudinal axis 174 of the outlet chamber and / or can be measured along the longitudinal axis of the outlet chamber.

[0040] The extension inlet chamber length 152 may be different from or greater than the outlet chamber length 172. For example, the ratio of the extension inlet chamber length 152 to the outlet chamber length 172 may be at least 1.0, at least 1.1, at least 1.2, at least 1.3, at least 1.4, at least 1.5, up to 2.0, up to 1.9, up to 1.8, up to 1.7, up to 1.6, up to 1.5, up to 1.4, up to 1.3, and / or up to 1.2. Examples of extension inlet chamber lengths 152 include lengths of at least 150 mm, at least 175 mm, at least 200 mm, at least 225 mm, at least 250 mm, at least 275 mm, at least 300 mm, at least 325 mm, at least 350 mm, at least 375 mm, at least 400 mm, at least 425 mm, at least 450 mm, at least 475 mm, at least 500 mm, up to 600 mm, up to 575 mm, up to 550 mm, up to 525 mm, up to 500 mm, up to 450 mm, up to 425 mm, up to 400 mm, up to 375 mm, up to 350 mm, up to 325 mm, and / or up to 300 mm.

[0041] In some examples, the extension inlet chamber 150 may have and / or be defined with an extension inlet chamber width 160, or an average extension inlet chamber width, as is probably best illustrated in Figures 5-6. In some examples, the extension inlet chamber width 160 may be measured perpendicular to, or at least substantially perpendicular to, the extension inlet chamber longitudinal axis 154, the driving flow axis 72, the slot longitudinal axis 194 of the extension slot 190, and / or the extension inlet chamber length 152, as is probably best illustrated in Figure 2.

Examples of extension inlet chamber widths 160 and / or outlet chamber widths 180 include widths of at least 20 mm, at least 25 mm, at least 30 mm, at least 35 mm, at least 40 mm, at least 45 mm, at least 50 mm, up to 75 mm, up to 70 mm, up to 65 mm, up to 60 mm, up to 55 mm, up to 50 mm, up to 45 mm, up to 40 mm, and / or up to 35 mm.

[0042] The intake chamber 260 may be molded, dimensionally determined, positioned, and / or oriented such that the intake fluid flow 76 is directed into the extension inlet chamber 150 such that the intake fluid flow 76 joins and / or mixes with the drive fluid flow 70 in and / or within the extension inlet chamber 150. As described above, supplying the drive fluid flow 70 to the drive fluid inlet port 220 may generate and / or create an attractive force or vacuum that provides the driving force for the intake fluid flow 76 to flow into the intake chamber 260 through the intake port 270 and / or through the intake chamber.

[0043] The intake port 270 may have any suitable arrangement and / or orientation within the air dispersion nozzle 100. For example, the intake port 270 may face the same or at least substantially the same direction as the extension outlet port 230. More specifically, the intake port 270 may be coplanar with the extension outlet port 230, at least substantially coplanar, parallel to the extension outlet port 230, and / or at least substantially parallel to the extension outlet port 230.

[0044] The intake chamber 260 may have an intake chamber length 264, or may extend along the intake chamber length 264. The intake chamber length 264 may extend parallel to, or at least substantially parallel to, the longitudinal axis 266 of the intake chamber and / or the intake flow axis 78. Additionally or alternatively, the intake chamber length 264 may extend perpendicular to, or at least substantially perpendicular to, the extension inlet chamber length 152 and / or the extension outlet chamber length 172.

[0045] The intake chamber length 264 may have and / or be defined by any suitable dimensions or relative dimensions. For example, the intake chamber length 264 may be a first intake chamber length threshold multiple of the inlet chamber height 158 ​​of the extension inlet chamber 150. Examples of the first intake chamber length threshold multiples may include at least 0.5, at least 0.6, at least 0.7, at least 0.8, at least 0.9, at least 1.0, up to 1.5, up to 1.4, up to 1.3, up to 1.2, up to 1.1, up to 1.0, up to 0.9, up to 0.8, and / or up to 0.7. As another example, the intake chamber length 264 may be a second intake chamber length threshold multiple of the outlet chamber height 178 of the extension outlet chamber 170. Examples of second intake chamber length threshold multiples may include at least 0.5x, at least 0.6x, at least 0.7x, at least 0.8x, at least 0.9x, at least 1.0x, up to 1.5x, up to 1.4x, up to 1.3x, up to 1.2x, up to 1.1x, and / or up to 1.0x.

[0046] The air dispersion nozzle 100 may have and / or be defined as having a nozzle total height 102 or an average nozzle total height, as perhaps best shown in Figure 2. In some examples, the nozzle total height 102 may be measured perpendicular to or at least substantially perpendicular to the longitudinal axis 154 of the extension inlet chamber, the extension inlet chamber length 152, the longitudinal axis 174 of the outlet chamber, the outlet chamber length 172, the extension inlet chamber width 160, the outlet chamber width 180, and / or the slot longitudinal axis 194. Additionally or alternatively, the nozzle total height 102 may be measured parallel to or at least substantially parallel to the outlet flow axis 92, the longitudinal axis 266 of the suction chamber, and / or the suction chamber length 264 of the suction chamber 260. Examples of nozzle heights of 102 may include heights of at least 75 mm, at least 80 mm, at least 85 mm, at least 90 mm, at least 95 mm, at least 100 mm, at least 105 mm, at least 110 mm, at least 115 mm, at least 120 mm, up to 150 mm, up to 145 mm, up to 140 mm, up to 135 mm, up to 130 mm, up to 125 mm, up to 120 mm, up to 115 mm, up to 110 mm, and / or up to 105 mm.

[0047] Referring again to Figure 2, the extension inlet chamber 150 may have and / or be defined as having an inlet chamber height 158. Additionally or alternatively, the extension outlet chamber 170 may have and / or be defined as having an outlet chamber height 178. The inlet chamber height 158 ​​and the outlet chamber height 178 may each be different and / or corresponding proportions or percentages of the total nozzle height 102. Examples of proportions include at least 10%, at least 15%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, up to 75%, up to 60%, up to 55%, up to 50%, up to 45%, up to 40%, up to 35%, up to 30%, and / or up to 25%.

[0048] The extension inlet chamber 150 may include any suitable structure, form, and / or configuration that can receive a flow of drive fluid 70 from a drive fluid inlet port 220 extending along the extension inlet chamber length 152 and / or supply a flow of slot fluid 206 to the extension outlet chamber 170 via an extension slot 190. In some examples, the extension inlet chamber 150 may be configured to direct the flow of drive fluid 70 toward and / or into the extension slot 190.

[0049] In some examples, as perhaps best illustrated by Figures 7 and 8, the cross-sectional area 156 of the extension inlet chamber 150 may decrease along the driving fluid axis 72 and / or in the direction of driving fluid. In some such examples, the maximum cross-sectional area 156 of the extension inlet chamber 150 may occur relatively near the driving fluid inlet port 220, and the minimum cross-sectional area 156 may occur relatively distal to the driving fluid inlet port. In some such examples, the cross-sectional area 156 of the extension inlet chamber 150 may decrease or decrease monotonically along the driving fluid axis and / or in the direction of driving fluid. In some such examples, the maximum cross-sectional area 156 of the extension inlet chamber 150 may be an inlet chamber area threshold multiple of the minimum cross-sectional area 156 of the extension inlet chamber. Examples of inlet chamber area threshold multipliers include at least 1.05x, at least 1.1x, at least 1.15x, at least 1.2x, at least 1.25x, at least 1.3x, at least 1.35x, at least 1.4x, at least 1.5x, at least 1.6x, at least 1.7x, at least 1.8x, at least 1.9x, up to 3.0x, up to 2.9x, up to 2.8x, up to 2.7x, up to 2.6x, up to 2.5x, up to 2.4x, up to 2.3x, up to 2.2x, up to 2.1x, up to 2.0x, up to 1.9x, up to 1.8x, up to 1.7x, up to 1.6x, and / or up to 1.5x. Such a configuration can improve the uniformity of the flow or flow rate of the slot fluid 206 by increasing the uniformity of the flow along the slot length 192 of the extension slot 190.

[0050] In some examples, the inlet chamber height 158, which may also be referred to herein as the height 158 ​​of the extension inlet chamber 150, may decrease along the driving flow axis 72 and / or in the direction of driving flow, or decrease monotonically. In some such examples, the maximum value of the inlet chamber height 158, which may also be referred to herein as the maximum height of the extension inlet chamber 150, may be at least an inlet chamber height threshold multiple of the minimum value of the inlet chamber height 158, which may also be referred to herein as the minimum height of the extension inlet chamber. Examples of high threshold multipliers for the inlet chamber include at least 1.05x, at least 1.1x, at least 1.15x, at least 1.2x, at least 1.25x, at least 1.3x, at least 1.35x, at least 1.4x, at least 1.5x, at least 1.6x, at least 1.7x, at least 1.8x, at least 1.9x, up to 3.0x, up to 2.9x, up to 2.8x, up to 2.7x, up to 2.6x, up to 2.5x, up to 2.4x, up to 2.3x, up to 2.2x, up to 2.1x, up to 2.0x, up to 1.9x, up to 1.8x, up to 1.7x, up to 1.6x, and up to 1.5x. Such a configuration can also improve the uniformity of the flow or flow rate of the slot fluid 206 by, for example, improving the uniformity of the flow along the slot length 192 of the extension slot 190.

[0051] In some examples, the extension inlet chamber width 160, which may also be referred to herein as the width 160 of the extension inlet chamber 150, may decrease along the driving flow axis 72 and / or in the direction of driving flow, or decrease monotonically. In some such examples, the maximum value of the extension inlet chamber width 160, which may also be referred to herein as the maximum width of the extension inlet chamber 150, may be at least an extension inlet chamber width threshold multiple of the minimum value of the extension inlet chamber width 160, which may also be referred to herein as the minimum width of the extension inlet chamber. Examples of extension inlet chamber width threshold multipliers include at least 1.05, at least 1.1, at least 1.15, at least 1.2, at least 1.25, at least 1.3, at least 1.35, at least 1.4, at least 1.5, at least 1.6, at least 1.7, at least 1.8, at least 1.9, up to 3.0, up to 2.9, up to 2.8, up to 2.7, up to 2.6, up to 2.5, up to 2.4, up to 2.3, up to 2.2, up to 2.1, up to 2.0, up to 1.9, up to 1.8, up to 1.7, up to 1.6, and up to 1.5. Such a configuration can also improve the uniformity of the flow or flow rate of the slot fluid 206 by, for example, improving the uniformity of the flow along the slot length 192 of the extension slot 190.

[0052] The extension outlet chamber 170 may include any suitable structure, form, and / or configuration that can generate a counter-rotating vortex 80 that can receive a flow of slot fluid 206 from an extension slot 190 extending along the outlet chamber length 172, and / or discharge an outlet fluid flow 90 through, for example, an extension outlet port 230. In some examples, the extension outlet chamber 170 may be molded to generate a counter-rotating vortex 80 and / or to direct the flow of slot fluid 206 toward the extension outlet port 230 as an outlet fluid flow 90.

[0053] In some examples, as perhaps best illustrated by Figures 7 and 8, the cross-sectional area 176 of the extension outlet chamber 170 may decrease along the driving fluid axis 72 and / or in the direction of driving fluid. In some such examples, the maximum cross-sectional area 176 of the extension outlet chamber 170 may occur relatively near the driving fluid inlet port 220, and the minimum cross-sectional area 176 may occur relatively distal to the driving fluid inlet port. In some such examples, the cross-sectional area 176 of the extension outlet chamber 170 may decrease along the driving fluid axis and / or in the direction of driving fluid, or decrease monotonically. In some such examples, the maximum cross-sectional area 176 of the extension outlet chamber 170 may be a threshold multiple of the outlet chamber area of ​​the minimum cross-sectional area 176 of the extension outlet chamber. Examples of exit chamber area threshold multipliers include at least 1.05x, at least 1.1x, at least 1.15x, at least 1.2x, at least 1.25x, at least 1.3x, at least 1.35x, at least 1.4x, at least 1.5x, at least 1.6x, at least 1.7x, at least 1.8x, at least 1.9x, up to 3.0x, up to 2.9x, up to 2.8x, up to 2.7x, up to 2.6x, up to 2.5x, up to 2.4x, up to 2.3x, up to 2.2x, up to 2.1x, up to 2.0x, up to 1.9x, up to 1.8x, up to 1.7x, up to 1.6x, and / or up to 1.5x. Such a configuration can improve the uniformity of the flow or flow rate of the outlet fluid 90 by, for example, improving the uniformity of the flow along the longitudinal axis 234 of the extension outlet port 230.

[0054] In some examples, the outlet chamber height 178, which may be referred to herein as the height 178 of the extension outlet chamber 170, may decrease along the driving flow axis 72 and / or in the direction of driving flow, or may decrease monotonically. In some such examples, the maximum value of the outlet chamber height 178, which may also be referred to herein as the maximum height of the extension outlet chamber 170, may be at least an outlet chamber height threshold multiple of the minimum value of the outlet chamber height 178, which may also be referred to herein as the minimum height of the extension outlet chamber. Examples of high threshold multipliers for the exit chamber include at least 1.05x, at least 1.1x, at least 1.15x, at least 1.2x, at least 1.25x, at least 1.3x, at least 1.35x, at least 1.4x, at least 1.5x, at least 1.6x, at least 1.7x, at least 1.8x, at least 1.9x, up to 3.0x, up to 2.9x, up to 2.8x, up to 2.7x, up to 2.6x, up to 2.5x, up to 2.4x, up to 2.3x, up to 2.2x, up to 2.1x, up to 2.0x, up to 1.9x, up to 1.8x, up to 1.7x, up to 1.6x, and / or up to 1.5x. Such a configuration can improve the uniformity of the flow or flow rate of the outlet fluid 90 by, for example, improving the uniformity of the flow along the longitudinal axis 234 of the extension outlet port 230.

[0055] In some examples, the outlet chamber width 180, which may be referred to herein as the width 180 of the extension outlet chamber 170, may decrease along the driving flow axis 72 and / or in the direction of the driving flow, or may decrease monotonically. In some such examples, the maximum value of the outlet chamber width 180, which may also be referred to herein as the maximum width of the extension outlet chamber 170, may be at least an outlet chamber width threshold multiple of the minimum value of the outlet chamber width 180, which may also be referred to herein as the minimum width of the extension outlet chamber. Examples of exit chamber width threshold multipliers include at least 1.05x, at least 1.1x, at least 1.15x, at least 1.2x, at least 1.25x, at least 1.3x, at least 1.35x, at least 1.4x, at least 1.5x, at least 1.6x, at least 1.7x, at least 1.8x, at least 1.9x, up to 3.0x, up to 2.9x, up to 2.8x, up to 2.7x, up to 2.6x, up to 2.5x, up to 2.4x, up to 2.3x, up to 2.2x, up to 2.1x, up to 2.0x, up to 1.9x, up to 1.8x, up to 1.7x, up to 1.6x, and / or up to 1.5x. Such a configuration can improve the uniformity of the flow or flow rate of the outlet fluid 90 by, for example, improving the uniformity of the flow along the longitudinal axis 234 of the extension outlet port 230.

[0056] As shown by the dashed line in Figure 2 and by the solid line in Figures 3 to 8, the air dispersion nozzle 100 may include an extension outlet structure 250. When present, the extension outlet structure 250 may be configured to receive the outlet fluid flow 90 from the extension outlet chamber 170 and / or discharge the outlet fluid flow from the air dispersion nozzle 100.

[0057] In some examples, the extension outlet structure 250 may define a diffuser mounting structure 252. The diffuser mounting structure 252 may be adapted, configured, molded, and / or dimensionally determined to accommodate an air diffuser 254 and / or to operably retain the air diffuser in the remainder of the air dispersion nozzle 100, when present. In some examples, the air dispersion nozzle 100 further includes an air diffuser 254 that can operably retain in the diffuser mounting structure 252. Examples of the diffuser mounting structure 252 may include a molded area for accommodating the air diffuser 254 and / or any suitable fasteners. Examples of the air diffuser 254 include a screen, grille, and / or louvre. The air diffuser 254 may be configured to diffuse the outlet fluid flow 90 and / or to supply back pressure to the extension outlet chamber 170, when present. Such a configuration can improve the uniformity of the flow or flow rate of the outlet fluid 90 by increasing the uniformity of the flow along the longitudinal axis 234 of the extension outlet port 230.

[0058] In some examples, the air dispersion nozzle 100 may include and / or be defined by a nozzle body 110. The nozzle body 110, when present, may define an extension inlet chamber 150, an extension outlet chamber 170, an extension slot 190, a driving fluid inlet port 220, an extension outlet structure 250, an inlet chamber 260, an inlet port 270, a sensor support 280, and / or a driving fluid acceleration structure 290. In some such examples, the nozzle body 110 may include and / or be a single integrated or single nozzle body 110, which may be formed and / or defined by an additive manufacturing process. In some examples, as shown in Figure 2, the nozzle body 110 may include and / or be a nozzle composite body 110 defined by at least two body elements 112 that are operably mounted to each other and define the nozzle body, or by only those two body elements 112. In some examples, the body elements 112 may be molded to be symmetrical with respect to each other, or at least substantially symmetrical.

[0059] The nozzle body 110 can define various components of the air dispersion nozzle 100 in any suitable manner. For example, as perhaps best shown in Figures 7-8, the nozzle body 110 may include an upper region 114 that can define the upper surface of the extension inlet chamber 150. As another example, the nozzle body 110 may define a first extension inlet chamber lateral region 116 that can define a first side of the extension inlet chamber 150, and / or a second extension inlet chamber lateral region 118 that can define a second side of the extension inlet chamber. As yet another example, the nozzle body 110 may define a first extension inlet chamber transition region 120 that can transition from the upper region 114 to the first extension inlet chamber lateral region 116, and / or a second extension inlet chamber transition region 122 that can transition from the upper region 114 to the second extension inlet chamber lateral region 118.

[0060] As another example, the nozzle body 110 may define a first extension inlet chamber tapered region 124 that tapers from the first extension inlet chamber lateral region 116 and at least partially defines the first side surface of the extension slot 190, and / or a second extension inlet chamber tapered region 126 that tapers from the second extension inlet chamber lateral region 118 and at least partially defines the second side surface of the extension slot 190. As shown in the figure, the first extension inlet chamber tapered region 124 and the second extension inlet chamber tapered region 126 may taper toward each other.

[0061] As yet another example, the nozzle body 110 may define a first outlet chamber upper tapered region 128 that may extend from the first extension inlet chamber tapered region 124 and / or be tapered away from the extension slot 190, and / or a second outlet chamber upper tapered region 130 that may extend from the second extension inlet chamber tapered region 126 and / or be tapered away from the extension slot. The first outlet chamber upper tapered region 128 and the second outlet chamber upper tapered region 130 may be tapered away from each other.

[0062] As another example, the nozzle body 110 may define a first outlet chamber lower tapered region 132 that extends from the first outlet chamber upper tapered region 128 and defines a first side surface of the extension outlet port 230, and / or a second outlet chamber lower tapered region 134 that extends from the second outlet chamber upper tapered region 130 and defines a second side surface of the extension outlet port 230. The first outlet chamber lower tapered region 132 and the second outlet chamber lower tapered region 134 may taper toward each other.

[0063] As yet another example, the nozzle body 110 may define a first outlet structure lateral region 136 that extends from the tapered region 132 below the first outlet chamber and defines a first side surface of the extension outlet structure 250. As yet another example, the nozzle body 110 may define a second outlet structure lateral region 138 that extends from the tapered region 134 below the second outlet chamber and defines a second side surface of the extension outlet structure.

[0064] As another example, the nozzle body 110 may define an inlet region 140, as perhaps best shown in Figures 3 to 5. The inlet region 140 may define at least partially the driving fluid inlet port 220 and / or extend from the upper region 114, the lateral region 116 of the first extension inlet chamber, and / or the lateral region 118 of the second extension inlet chamber.

[0065] As yet another example, the nozzle body 110 may define a terminal region 142, as perhaps best shown in Figure 6. The terminal region 142 may define the distal end of the inlet of the air dispersion nozzle 100. Additionally or alternatively, the terminal region 142 may extend from the upper region 114, the lateral region 116 of the first extension inlet chamber, the lateral region 118 of the second extension inlet chamber, the transition region 120 of the first extension inlet chamber, the transition region 122 of the second extension inlet chamber, the tapered region 124 of the first extension inlet chamber, the tapered region 126 of the second extension inlet chamber, the upper tapered region 128 of the first outlet chamber, the upper tapered region 130 of the second outlet chamber, the lower tapered region 132 of the first outlet chamber, the lower tapered region 134 of the second outlet chamber, the lateral region 136 of the first outlet structure, and / or the lateral region 138 of the second outlet structure.

[0066] As shown by dashed lines in Figure 2 and by solid lines in Figures 4 and 10, the air dispersion nozzle 100 may include a separation structure 300. When present, the separation structure 300 may extend between the extension outlet chamber 170 and the intake chamber 260 and / or fluidly separate the extension outlet chamber 170 and the intake chamber 260. In some examples, the separation structure 300 may define at least a portion of a region of the extension outlet chamber 170 and / or the intake chamber 260, at least a portion of a region of the extension outlet chamber 170 and / or the intake chamber 260, and / or form the boundary of a region of the extension outlet chamber 170 and / or a region of the intake chamber 260. In some examples, a driving fluid acceleration structure 290 may be shaped and / or positioned to accelerate the driving fluid flow 70 before it passes through the separation structure 300.

[0067] In some examples, the separation structure 300 may include an aerodynamically molded surface 310, as perhaps best illustrated in Figures 2 and 10. The aerodynamically molded surface 310, when present, may at least partially define a region 262 of the intake chamber 260 that leads into the extension inlet chamber 150. In other words, the aerodynamically molded surface 310 may at least partially define a transition region between the intake chamber 260 and the extension inlet chamber 150, such as region 262. The aerodynamically molded surface 310 may be molded to direct the intake fluid flow 76 toward and / or into the extension slot 190 and / or extension outlet chamber 170, for example, through the extension inlet chamber 150. Examples of aerodynamically molded surfaces 310 and / or region 262 include convex surfaces and / or Coanda surfaces.

[0068] In some examples, the separation structure 300 may include an outlet fluid flow direction redirection structure 320, as shown in Figures 2 and 10. The outlet fluid flow direction redirection structure 320 may be located within and / or at least partially define the extension outlet port 230. The outlet fluid flow direction redirection structure 320 may be molded, dimensionalized, and / or positioned to direct the outlet fluid flow 90 away from, or at least partially away from, the inlet fluid flow 76 and / or the inlet port 270. In other words, the outlet fluid flow direction redirection structure 320 may be configured to reduce the proportion of the outlet fluid flow 90 that is discharged from the air dispersion nozzle 100 through the extension outlet port 230 and then re-enters the air dispersion nozzle 100 through the inlet port 270 as the inlet fluid flow 76. An example of the outlet fluid flow direction redirection structure 320 includes a protruding region that projects toward and / or away from the extension outlet port 230.

[0069] The air dispersion nozzle 100 according to this disclosure may be relatively simpler and / or contain fewer components compared to conventional air dispersion nozzles. Such conventional air dispersion nozzles often rely on internal baffles, rectifiers, and / or flow guides to provide a desired level of fluid flow uniformity, which makes conventional air dispersion nozzles more expensive and / or more complex to manufacture, install, and / or maintain. In light of the above and further the description of the air dispersion nozzle 100 shown in Figures 2 to 10, it falls within the scope of this disclosure that the air dispersion nozzle 100 according to this disclosure may not include, or may not include, baffles, rectifiers, and / or flow guides extending and / or protruding inside and / or between the extension inlet chamber 150, extension outlet chamber 170, extension slot 190, driving fluid inlet port 220, and / or extension outlet port 230.
