Description

Technical Field

[0001] This disclosure relates to the field of cloud uniformity measurement, and more specifically, to a water droplet separation measurement device. Background Technology

[0002] Icing wind tunnels are crucial ground-based facilities for aircraft icing research and the verification of aircraft component anti-icing and de-icing systems, providing vital data support for aircraft icing airworthiness certification. To meet airworthiness certification requirements, icing wind tunnels must conduct calibration and evaluation of cloud and fog field quality, including the uniformity of icing cloud and fog, specifically the spatial uniformity of the liquid water content (LWC) in the icing cloud and fog within the wind tunnel test section. A commonly used method for measuring cloud and fog field uniformity in icing wind tunnels is the grid icing method, which determines uniformity by measuring the relative thickness distribution of ice on the grid.

[0003] If the conventional grid icing method is used to measure the uniformity of clouds and fog in Appendix O (whose droplet diameter is significantly larger than that required for conventional icing environments in Appendix C), the presence of large-diameter droplets, which are large in size and high in temperature, results in breakage, splashing, and backflow upon impact with the grid. These droplets cannot condense instantly; some are carried away by the airflow after splashing, while others adhere to the backflow. Furthermore, the dynamic behaviors of breakage and splashing are highly random and variable, leading to a low and unstable actual collection rate of large-diameter droplets, affecting the accurate assessment of cloud and fog field uniformity. In addition, conventional trough grids lack pressure relief vents, causing backflow after airflow enters, resulting in turbulent and unsteady flow at the inlet, affecting the stability of droplet capture. Moreover, conventional grids do not have devices specifically designed to collect droplets of a target size; instead, they collect droplets of all sizes uniformly. Since the large-diameter water droplets in clouds and fog generally account for a small proportion of the total mass, and the collection rate of large-diameter water droplets (with a diameter of approximately 300 μm and above, the specific range depends on the operating conditions) is low as mentioned above, when using conventional grid uniformity measurement methods to collect water droplets, the actual mass of the large water droplets collected accounts for a small proportion of the total collected mass, and may even be less than the uniformity requirement (±20%). This makes it impossible to accurately reflect the uniformity of the distribution of large water droplets, let alone determine the uniformity of the distribution of large water droplets in different diameter ranges.

[0004] Therefore, there is a need to propose an improved water droplet separation and measurement device that can solve the problems and defects existing in the prior art. Summary of the Invention

[0005] The purpose of this invention is to provide a water droplet separation and measurement device that can effectively collect large-diameter water droplets and water droplets of different diameter ranges.

[0006] According to this disclosure, a water droplet separation measuring device is proposed for capturing water droplets, comprising: a plurality of water droplet collectors connected to each other, wherein each water droplet collector extends along a longitudinal axis and includes: a housing including an open, opposite top end and a bottom end, defining a collection cavity between the top end and the bottom end, wherein the longitudinal section of the collection cavity is spindle-shaped; a separation assembly disposed in the collection cavity defining a primary collection region; and a water collector disposed in the collection cavity defining a secondary collection region; wherein the secondary collection region is located below the primary collection region, and wherein at least a portion of the size of the primary collection region is adjustable to adjust the particle size range of the water droplets captured in the secondary collection region.

[0007] The water droplet collector disclosed herein uses a primary collection area to separate water droplets smaller than the target particle size using inertia, and a secondary collection area to separate water droplets smaller than the target particle size in a secondary collection area. It also prevents water droplets with a particle size not smaller than the target size from breaking up and flowing back out of the secondary collection area, ensuring collection effectiveness and stability. Furthermore, the water droplet collector of this disclosure adjusts the size of the primary collection area to regulate the range of water droplets allowed to enter the primary collection area and thus the secondary collection area, thereby achieving the collection of water droplets with different particle size ranges.

[0008] According to another aspect of this disclosure, the collecting cavity sequentially includes an inlet section, a widening section, and a narrowing section along the longitudinal direction, wherein the transverse width of the inlet section remains substantially constant along the longitudinal direction; the widening section is adjacent to the inlet section, wherein the transverse width of the widening section gradually widens along the longitudinal direction; and the narrowing section is adjacent to the widening section, wherein the transverse width of the narrowing section gradually narrows along the longitudinal direction.

[0009] According to another aspect of this disclosure, the separation component is arranged in the widening section of the collection chamber, wherein the width of the primary collection area gradually widens along the longitudinal direction.

[0010] According to another aspect of this disclosure, the separating component includes an upper end and a lower end opposite to each other, wherein the separating component includes an upper adjusting component at the upper end, the upper adjusting component being configured to lengthen or shorten the width of the primary collection area at the upper end, and wherein the separating component includes a lower adjusting component at the lower end, the lower adjusting component being configured to lengthen or shorten the width of the primary collection area at the lower end.

[0011] According to another aspect of this disclosure, the separating assembly further includes a body comprising a first sub-body and a second sub-body symmetrically distributed about a longitudinal axis, each sub-body having an upper end and a lower end opposite to each other. The upper adjustment assembly includes a first upper adjustment member and a second upper adjustment member, the first upper adjustment member being pivotally connected to the upper end of the first sub-body, and the second upper adjustment member being pivotally connected to the upper end of the second sub-body. The lower adjustment assembly includes a first lower adjustment member and a second lower adjustment member, the first lower adjustment member being pivotally connected to the lower end of the first sub-body, and the second lower adjustment member being pivotally connected to the lower end of the second sub-body.

[0012] According to another aspect of this disclosure, a water collector is arranged in a tapering section of the collection chamber, wherein the water collector includes: a first water collecting bar and a second water collecting bar, the first water collecting bar and the second water collecting bar being arranged axially symmetrically about a longitudinal axis above the bottom end of the housing, wherein the transverse width of the section of the secondary collection area defined by the first water collecting bar and the second water collecting bar is tapering in the longitudinal direction; and a water storage element, which is connected to both the first water collecting bar and the second water collecting bar below these water collecting bars, wherein the water storage element is arranged below the bottom end of the housing.

[0013] According to another aspect of this disclosure, the first water collecting bar and the first lower adjusting member are spaced apart in the lateral direction to form a first pressure relief port, while the second water collecting bar and the second lower adjusting member are spaced apart in the lateral direction to form a second pressure relief port.

[0014] According to another aspect of this disclosure, the water storage element is a hollow container including an open upper end and a closed lower end, wherein a drain plug is removably inserted into the lower end of the water storage element.

[0015] According to another aspect of this disclosure, a pair of fixing plates are also included, which are fixed to the housing relative to each other, wherein the pair of fixing plates secure the separation assembly and the water collector between the pair of fixing plates.

[0016] According to another aspect of this disclosure, a plurality of water droplet collectors are arranged orthogonally at the top of their housings, such that the tops of the housings of the plurality of water droplet collectors are combined and arranged in a grid pattern.

[0017] The water droplet separation measuring device of the present invention uses a separation component and a water collector arranged below the separation component. This allows for primary water droplet separation at the upper end of the separation component via the gap between the separation component and the outer casing, utilizing the inertia of falling water droplets to capture water droplets within the target particle size range into the primary collection area defined by the separation component. At the lower end of the separation component, a pressure relief port between the separation component and the water collector prevents airflow backflow and enables secondary water droplet separation, further filtering water droplets outside the target particle size range and capturing water droplets within the target particle size range into the secondary collection area defined by the water collector, ultimately allowing them to fall into the water storage container. Furthermore, pivotable upper and lower adjustment components are respectively provided at the upper and lower ends of the separation component, allowing the lateral width of the upper and lower ends of the primary collection area to be changed, thereby adjusting the particle size range of the water droplets captured in the primary collection area and thus in the secondary collection area, enabling the capture of water droplets with different particle size ranges.

[0058] The following description of specific embodiments of the invention refers to the accompanying drawings, which illustrate particular embodiments in which the invention can be practiced. The embodiments are intended to describe aspects of the invention in sufficient detail to enable those skilled in the art to practice it. Other embodiments may be utilized and changes may be made without departing from the scope of the invention. Therefore, the following description of specific embodiments should not be considered limiting. The scope of the invention is defined only by the appended claims and the full scope of their equivalents. The same reference numerals are used throughout the drawings and specific embodiments to refer to the same or similar parts.

[0059] In this text, the longitudinal direction Y is the direction extending downwards along the longitudinal axis L of the water droplet collector 1 of the water droplet separation measuring device 100, and the transverse direction X is the direction perpendicular to the longitudinal direction Y. The directional terms "upper," "lower," "top," and "bottom" refer to the positions of the water droplet collector 1 of the water droplet separation measuring device 100 when it is in a certain position. Figure 3 The working position shown is relative to the longitudinal direction Y. The term "lateral width" refers to the width or dimension of the component in the lateral direction X.

[0060] Figure 1 A top view of a water droplet separation measuring device 100 is shown, which includes a plurality of water droplet collectors 1 connected to each other in the form of a grid. For simplicity, only two water droplet collectors 1 are shown as an example. Figure 2 It shows Figure 1 A partially enlarged perspective view of the water droplet separation measuring device 100, showing the specific structure of the two water droplet collectors 1, and the outer shell 2 and fixing plate 7 of the water droplet collector 1 are drawn in perspective to clearly show the components in the collection chamber 201 of the water droplet collector 1. Figure 3 A longitudinal sectional view of the water droplet collector 1 is shown.

[0061] As shown in the figure, the water droplet collector 1 extends along the longitudinal axis L and generally includes a housing 2 defining a collection chamber 201, a separation component 3 disposed in the collection chamber 201, and a water collector 4 partially located in the collection chamber 201 and disposed below the separation component 3.

[0062] The outer shell 2 of the water droplet collector 1 includes a first half-shell 21 and a second half-shell 22 arranged symmetrically about the longitudinal axis L. The first half-shell 21 and the second half-shell 22 are symmetrically contoured, zigzag-shaped plates. Figure 2 As shown, a pair of fixing plates 7 are fixed to the first half-shell 21 and the second half-shell 22 opposite to each other. The shape of the pair of fixing plates 7 is such that they fit the symmetrical zigzag shape of the first half-shell 21 and the second half-shell 22, so that the first half-shell 21, the second half-shell 22 and the pair of fixing plates 7 surround to form a collecting cavity 201, wherein the longitudinal section of the collecting cavity 201 is as shown in the figure. Figure 3The shape is spindle-shaped. Because the first half-shell 21 and the second half-shell 22 are arranged at intervals, the top end 26 and the bottom end 27 of the outer shell 2 are open to allow water droplets to fall through the collection chamber 201.

[0063] Still Figure 2 As shown, in two adjacent water droplet collectors 1, the second half-shell 22 of one water droplet collector 1 is longitudinally joined to the first half-shell 21 of the other water droplet collector 1, and the tops 26 of the outer shells 2 of the two adjacent water droplet collectors 1 are perpendicular to each other and lie in the same horizontal plane. Multiple water droplet collectors 1 are arranged orthogonally to each other such that the tops 26 of the outer shells 2 of these water droplet collectors 1 are arranged in a grid pattern. From a top view, the overall outline is as follows: Figure 1 As shown.

[0064] like Figure 3 As shown, the collecting cavity 201 extends from the top 26 to the bottom 27 of the outer shell 2, and from top to bottom along the longitudinal direction Y, it includes an inlet section 23, a widening section 24, and a narrowing section 25. The width of the inlet section 23 remains essentially constant along the longitudinal direction Y; the widening section 24 is adjacent to the inlet section 23, and its width gradually widens along the longitudinal direction Y; the narrowing section 25 is adjacent to the widening section 24, and its width gradually narrows along the longitudinal direction Y. The inlet section 23, the widening section 24, and the narrowing section 25 transition smoothly, making the longitudinal section of the collecting cavity 201 a spindle shape without bends, preferably a truncated spindle shape.

[0065] The separation component 3 is arranged in the collection chamber 201, and is... Figure 2 As shown, it is fixed to the pair of fixing plates 7. The separating assembly 3 is arranged in the widening section 24 of the collecting cavity 201, including an upper end 31 and a lower end 32 opposite to each other. The separating assembly 3 includes an upper adjusting assembly 33 at its upper end 31 and a lower adjusting assembly 34 at its lower end 32, and includes a body 35 between the upper adjusting assembly 33 and the lower adjusting assembly 34. The upper adjusting assembly 33 and the lower adjusting assembly 34 are pivotable about the body 35.

[0066] More specifically, the main body 35 of the separating component 3 includes a first sub-body 351 and a second sub-body 352 arranged symmetrically about the longitudinal axis L. The first sub-body 351 is pivotally connected to a first upper adjusting member 331 at its upper end 31 and to a first lower adjusting member 341 at its lower end 32. The first sub-body 351, the first upper adjusting member 331, and the first lower adjusting member 341 are preferably integrally shaped as a spindle. Similarly, the second sub-body 352 is pivotally connected to a second upper adjusting member 332 at its upper end 31 and to a second lower adjusting member 342 at its lower end 32. The second sub-body 352, the second upper adjusting member 332, and the second lower adjusting member 342 are preferably integrally shaped as a spindle. The first upper adjusting member 331 and the second upper adjusting member 332 combine to form an upper adjusting component 33, while the first lower adjusting member 341 and the second lower adjusting member 342 combine to form a lower adjusting component 34.

[0067] The separating assembly 3 defines a primary collection region 301 between the spaced-apart first sub-body 351, first upper adjustment member 331, and first lower adjustment member 341, and between the second sub-body 352, second upper adjustment member 332, and second lower adjustment member 342. This primary collection region 301 extends between the upper end 31 and the lower end 32 of the separating assembly 3. The lateral distance between the first sub-body 351 and the second sub-body 352 gradually widens along the longitudinal direction Y, such that the lateral width of the primary collection region 301 generally widens along the longitudinal direction Y.

[0068] When a group of water droplets enters from the top 26 of the water droplet collector 1 and descends through the inlet section 23 and the widening section 24 of the collection chamber 201, the airflow is deflected to both sides of the longitudinal axis L due to the expansion of the flow path, generating lateral velocity and causing the water droplets to move laterally. Because of the difference in inertia between water droplets of different sizes, the effect on the droplets is inversely proportional to their size; the smaller the droplet size, the more severe the lateral deflection. This causes smaller droplets to flow out of the water droplet collector 1 through the gap between the separation component 3 and the outer shell 2 via the bottom 27 of the outer shell 2, while larger droplets experience less lateral deflection and can flow into the primary separation region from the upper 31 of the separation component 3. Thus, primary separation of water droplets smaller than the target particle size is achieved.

[0069] The first upper adjustment member 331 and the second upper adjustment member 332 can pivot around the upper end 31 of the first sub-body 351 and the upper end 31 of the second sub-body 352, respectively, so that the width of the primary collection area 301 at the upper end 31 of the separation component 3 can be lengthened or shortened; while the first lower adjustment member 341 and the second lower adjustment member 342 can pivot around the lower end 32 of the first sub-body 351 and the lower end 32 of the second sub-body 352, respectively, so that the width of the primary collection area 301 at the lower end 32 of the separation component 3 can also be lengthened or shortened.

[0070] The upper adjustment member, composed of the first upper adjustment member 331 and the second upper adjustment member 332, adjusts the lateral width of the primary collection area 301 at the upper end 31 of the separation component 3, thereby enabling the capture of water droplets with different particle sizes. Specifically, the wider the lateral width of the primary collection area 301 at the upper end 31 of the separation component 3, the larger the lateral offset (i.e., the smaller the particle size) of water droplets can enter the primary collection area 301; conversely, the narrower the lateral width of the primary collection area 301 at the upper end 31 of the separation component 3, the larger the particle size of water droplets allowed to enter the primary collection area 301. Therefore, different target particle sizes can be set, and the upper adjustment member can be pivoted according to the set target particle size. Specifically, the first upper adjustment member 331 and the first lower adjustment member 341 are pivoted to allow water droplets with a particle size not smaller than the target particle size to enter the primary collection area 301, while a portion of the water droplets with a particle size smaller than the target particle size flow out of the water droplet collector 1 through the gap between the separation component 3 and the outer shell 2. Thus, it is possible to collect water droplets with different particle sizes.

[0071] Now turn to collector 4. Collector 4 is as follows... Figure 2 , Figure 3 The secondary collection region 401 is arranged in the tapered section 25 of the collection cavity 201, below the separation assembly 3, and defines the secondary collection region 401. The secondary collection region 401 is located below the primary collection region 301, and preferably as shown... Figure 3 The adjacent primary collection area 301 is shown. The water collector 4 includes a first water collecting strip 41 and a second water collecting strip 42 arranged symmetrically about the longitudinal axis L, and a water storage component 43 connecting the first water collecting strip 41 and the second water collecting strip 42. The lateral distance between the first water collecting strip 41 and the second water collecting strip 42 gradually decreases along the longitudinal direction Y, so that the lateral width of the section of the secondary collection area 401 defined between the first water collecting strip 41 and the second water collecting strip 42 generally decreases along the longitudinal direction Y. The water storage component 43 is a hollow container, with its open upper end 431 connected to the first water collecting strip 41 and the second water collecting strip 42, and a drain plug 44 removably inserted at its closed lower end 432 to facilitate the discharge of collected water droplets, thereby enabling subsequent measurement of water droplet distribution uniformity.

[0072] Preferably, the upper end 431 of the water storage component 43, which connects to the first water collecting bar 41 and the second water collecting bar 42, is flush with the bottom end 27 of the outer casing 2, such that the first water collecting bar 41 and the second water collecting bar 42 are above the bottom end 27 of the outer casing 2, while the water storage component 43 is below the bottom end 27 of the outer casing 2. However, the invention is not limited to this; the entire water collector 4 can also be positioned above the bottom end 27 of the outer casing 2, or the first water collecting bar 41 and the second water collecting bar 42 can also be partially located below the bottom end 27 of the outer casing 2.

[0073] Preferably, the first water collecting bar 41 and the first lower adjusting member 341 are spaced apart in the lateral direction X to form the first pressure relief port 5, while the second water collecting bar 42 and the second lower adjusting member 342 are spaced apart in the lateral direction X to form the second pressure relief port 6.

[0074] When water droplets flow through the primary collection area 301 and pass through the lower end 32 of the separation component 3, since the primary collection area 301 is also gradually widened, the water droplets are still affected by the expansion of the flow path and are laterally deflected. Small-diameter water droplets with greater lateral deflection flow out of the water droplet collector 1 through the first pressure relief port 5 and the second pressure relief port 6 without entering the secondary collection area 401. Large-diameter water droplets (or water droplets within the target particle size range) with less lateral deflection continue to fall into the secondary collection area 401 and eventually fall into the water storage container 43. At the same time, since the lower end of the water collector 4 is closed, there are dead water zones in the first water collecting bar 41 and the second water collecting bar 42. The airflow is slowed down and flows back due to the dead water zones in the first water collecting bar 41 and the second water collecting bar 42. Small-diameter water droplets are greatly affected by the airflow and are discharged from the first pressure relief port 5 and the second pressure relief port 6. Large-diameter water droplets, due to their greater inertia, will directly hit the walls of the first water collecting bar 41 and the second water collecting bar 42 and then flow into the water storage container 43 and be stored there. Thus, the two-stage separation of water droplets with a particle size smaller than the target particle size is completed.

[0075] Furthermore, when the upper adjusting member adjusts the width of the primary collection area 301 at the upper end 31 of the separation component 3 as described above, it will cause a change in flow rate. For example, when its width is increased, more water droplets are allowed to enter the primary collection area 301, and the flow rate increases; while when its width is shortened, fewer water droplets are allowed to enter the primary collection area 301, and the flow rate decreases. Therefore, it is necessary to adjust the lower adjusting member to correspondingly adjust the flow rate entering the secondary collection area 401 to ensure a stable flow rate of water droplets falling into the water storage component 43. Specifically, the larger the size of the first pressure relief port 5 and the second pressure relief port 6, the more water droplets are allowed to flow out of the water droplet collector 1 through the first pressure relief port 5 and the second pressure relief port 6, and the smaller the flow rate of water droplets entering the secondary collection area 401; conversely, the smaller the size of the first pressure relief port 5 and the second pressure relief port 6, the larger the flow rate of water droplets entering the secondary collection area 401. Therefore, the first lower adjusting member 341 and the second lower adjusting member 342 can be pivoted to adjust the size of the first pressure relief port 5 and the second pressure relief port 6, thereby ensuring that the flow rate of water droplets entering the secondary collection area remains stable regardless of the flow rate of water droplets entering the primary collection area.

[0076] The water droplet separation and measuring device of this invention achieves the separation of water droplets of different sizes by utilizing a spindle-shaped overall profile and paired separating components. A pressure relief port is provided between the separating component and the water collector to prevent negative impacts from airflow backflow, thus solving the problem of poor droplet capture stability in existing water droplet separation and measuring devices. An upper adjustment component is provided at the upper end of the separating component to allow adjustment of the lateral width at the upper end of the primary collection area defined by the separating component, thereby allowing adjustment of the range of droplet sizes captured in the primary collection area and thus in the water collector. This solves the problem that existing water droplet separation and measuring devices cannot capture water droplets of different size ranges, thus making it impossible to determine the uniformity of the distribution of large water droplets in different size segments. Furthermore, a lower adjustment component is provided at the lower end of the separating component to adjust the flow rate of water droplets entering the water collector, ensuring the stability of the water droplet flow rate.
