FLUID CURTAIN BASED CONVEYOR PRODUCTION DEVICE

Abstract

The invention is a fluid curtain-based conveying device (like wings) consisting of a flat plate (11) which is a carrier surface, and fluid curtains (12,13,14) formed by the fluid jets (8,9,10) ejected from the slits located on the rear, right and left edges of this plate (11). The fluid source to feed these fluid curtains (12,13,14) may be a pump, compressor or fluid transfer. The invention is based on the fact that the fluid curtains (12,13,14), formed by the fluid jet outlet channels (3,4,5) located on three edges of a plate (11), create a flow field of high static pressure in the lower region of the plate (11) when subjected to free flow, and thus create a lifting force on the plate (11) similar to that of wings. Therefore, the invention is called a fluid curtain-based conveying device.The invention restricts the exit of the free stream from under the plate (11) with fluid baffles (12,13,14) and forces it to change direction, so that the static pressure increases with the ram effect while the velocity parallel to the plate decreases. As a result, high lift force is obtained with static pressure, while the drag force decreases due to the reduced velocity. The system can operate in air, water or similar fluid media and produces very high lift / drag ratios (L / D) in both low and high speed regimes. The invention is an innovative solution that can be modularly integrated into air and marine vessels, turbine blades, propellers, hydrofoil structures and other flow-based transport / energy systems, capable of generating transport and providing active flow control (Figure 2c – Figure 3).

1 TARIFF 5 FLUID CURTAIN BASED CONVEYOR PRODUCTION DEVICE 1. The Technical Field of the Invention This invention has implications for aerospace engineering, fluid mechanics, transportation systems, and Wing systems are related to fluid mechanics and aerodynamics / hydrodynamics. It produces buoyancy force. Especially in fluid environments such as air or water. By creating fluid jet curtains beneath moving surfaces, it provides high lift. Lifting force that enables the achievement of high lifting force and low drag force. It is related to the production and active flow control systems. 2. State of the Technology Today, the lift-to-drag ratio (L / D ratio) of a conveying surface is 15% of the efficiency of the conveying surface. This is one of the most important aerodynamic parameters determining the system's performance. In known systems, this ratio is:  Passive methods (e.g. wing geometry optimization, w nglet (addition, use of Gurney flap)  Active methods (e.g., boundary layer suction, blowing, microjets) efforts are being made to increase it. 20 However, these methods lift the flow by creating a pressure difference around the surface. Although it enables production, it avoids problems such as high drag or complex mechanical structures. He brings it along. For example, WIG (Wing n Ground) vehicles can achieve up to 30% L / D increase using ground effects. It provides protection; however, it is sensitive to surface height variations. 25 Similarly, Gurney flap applications also increase lift while reducing drag. It makes it bigger. Therefore, a car that can simultaneously reduce drag while achieving high lift. Method 1 is not found in the literature. 2 3. Purpose of the Invention 5 The main purpose of this invention is,  High load-to-drag (L ft / Drag) ratio carrier It is to develop.  Without the need for classic solid surface geometries,  Fluid curtains created by fluid jets surround the static pressure 10 by creating a pressure zone (ram pressure zone), -high lift force- to produce,  By reducing the flow velocity parallel to the surface, the drag force is reduced and This allows for very high lift / drag ratios.  Ability to control transport and drag with fluid curtains 15 The secondary objectives are as follows:  Modular lifting systems that can be integrated into existing aircraft or sea vehicles. system development,  Energy efficiency in turbine blades, propellers, or hydroelectric systems increase, 20  To ensure environmental and economic efficiency in high-speed transportation. 4.

It consists of fluid curtains created by ejecting fluids. 25 These jet curtains do not prevent external flow from directly entering beneath the plate, but they do prevent it from exiting. obstructions and force changes in direction. Thus, the changing flow of the incoming free current... Momentum is converted into pressure; this results in high pressure below the surface n. It creates and therefore produces bearing force (l ft) on the plate. At the same time, the bottom 30 The drag force decreases as the flow velocity parallel to the plate surface in the region decreases. (Drag) decreases. Thus, while the lift force increases, the drag force decreases. 3 Lift / drag, one of the most important performance criteria in production, is 5. The rate is very high. In validations performed using CFD (Computational Fluid Dynamics) analyses, water In tests conducted in the environment with speeds ranging from 30–60 m / s;  High static pressure regions are formed,  The lift force is much higher than that of rigid wing geometries, 10  The L / D ratio has been observed to reach very high values.

Detailed Description of the Invention 5 In all forms, fluids move across plates in accordance with established practices in the field of mechanics. (11) It is assumed that the constant is the fluid and it is in relative motion. (This approach, wind This scenario is similar to the tunnel test. In reality, this scenario involves the movement of the plate (11) and the fluid. This is physically equivalent to the case where t is constant. This type of relativistic modeling is used for fluids. (It is commonly used in mechanical analysis.) 10 Figures 2a, 2b, 2c, and 2d illustrate the aerodynamic effects of the invention. A detailed view of the sample plate (11) used is given. The bottom of the plate (11), Fluid outlet openings (1) located on the side and rear edges; left jet outlet channel (5), rear jet outlet channel (4), right jet outlet channel (3) through, flat plate (11) left left side fluid curtain (14), right side fluid curtain 15 fluid curtains including curtain (12), back edge fluid curtain (13) (12,13,14) is aimed to be created. Figure 3, Figure 6. The plate used as an example (11) is flat in shape with dimensions of 1000 × 1000 mm. 2a. Reference numbers are used in Figures 2 and 3 to standardize the description. ver lm şt r. 20 The invention is a fluid curtain-based conveyor system (wings, etc.) and the concept is... To illustrate, an example of a load-bearing surface is shown in Figures l-2a and l-2c. It is designed. The carrier surface is a flat plate (11), rear jet outlet channel (4), right / left side jet outlet channels (3, 5), plate (11), rear part of the plate (target plate) (7), front of the plate The front part (6), rear and front edges (1,2) are designed. The target plate is 25 (7) three sides are surrounded by fluid jet outlet channels (3,4,5), front plate (6) se, plate (11) is the part immediately in front of the rear but not surrounded by jet ducts. Figure 1-2c. The right, left and rear edges of the rear part of the plate (7) seen in Figure 1-2c. Fluid jets exiting from outlet channels (3,5,4) downwards and into the main stream (8,9,10) These jets (3, 4, 5) form fluid curtains (12, 14, 13). Figure 3. 30 Fluid jets emerging from the right edge (8), fluid jets emerging from the left edge (9) and the rear Liquid jets (10) coming out of the edge of the pump supplying pressurized fluid (air, water etc.) or fed by compressor etc. (pump and compressor producing fluid jets (8,9,19)) 6 vs. fluid source – not significant in terms of invention – shown in Figure 5 (not shown) Figure 3. When fluid curtains (12,13,14) are created under the plate (11) to the main stream, this The curtains interact with the free current, creating a pressure area under the plate and therefore will create a lifting force as shown in Figure 6. The back and sides are with fluid curtains (12,13,14) The rear part of the plate (target plate) (7) (figure 2-c), most of the lifting force is 10 It is the part where it is produced. However, the front, which does not have fluid curtains (!2,13,14) on its sides. A small amount of lifting force is produced in the plate (11) and (6) (due to the effect of the rear plate). Therefore). Lifting force, free stream velocity, fluid curtain thickness (!2,13,14), shape, Flow rate is proportional to fluid properties (density, temperature, etc.). Formation and reduction of lifting force with example values: Free flow (e.g., n 30 15 Let the water flow move at a speed of m / s towards the bottom of plate (11). left fluid curtain (14), back fluid curtain (13) and right fluid curtain (12) this It surrounds the area, creating a barrier to external flow entering that area, while The speed of the free current coming parallel to the plate (11) slows down in the direction of the plate (11). The free current tends to change direction downwards. Under these conditions, the plate (11) 20 Underneath, the ram effect creates a high static pressure on the plate (11) above, figure-3, Figure 6 Figure 8. The pressure difference on the surface of the plate (11) (upper low pressure – lower high pressure) This is why a net lift force (L) is generated. Also, the flow parallel to the plate (11) in the lower region. As the speed decreases, the wall shear stress (τₜₐₗ) decreases and the drag (D) decreases. 25 In the absence of fluid barriers (!2,13,14); a flat surface exposed to parallel free flow In plate (11) (kgb in figures l-1a and l-1b), theoretically no lifting force is generated. However As seen in figures l-7, l-8, l-9, l-10, l-11 and l-12, this plate (11) When fluid curtains (12.13.14) are formed around it, plate (11) is still parallel Despite being exposed to free current, a transport force is generated. 30 In this configuration, the majority of the lifting force occurs on the target plate (7). If the amount of material transport is not present on the front plate (6), this effect is not present on the target plate (7). is lower in comparison. According to the system design, the front plate (6) can be completely removed or added It can be strengthened with shielding (Figure 2b). 7 The fluid jet exiting from the left edge nn (8), the fluid jet exiting from the right edge nn (9) and the rear 5 The position, shape, direction and flow rate of the fluid jet coming out of the edge (10) are important, of the plate (11) They do not prevent current from passing under the plate (11) Figure 6. Pressure formed under the plate (11) This fluid changes with its properties. In fact, the lift force of these fluid jets (8,9,10) Flow rates and speeds, etc., can be controlled by changing them. Another explanation for the occurrence of transport in the target region is as follows: 10 in parallel current Fluid curtains (12,13,14) on the side and rear edges of the plate (11) When formed (figure l-4, figure l-6, figure l-8), a stagnant or They create a region where the fluid's velocity slows down. Therefore, the energy contained within is converted into pressure as the current slows down and transported (L ft). It creates. Also, this deceleration is due to friction on the lower surface of the plate (11). The drag (n) causes the vehicle to fall. Thus, the L ft / Drag ratio is very high. A high-performance, load-bearing surface (wing) is obtained. This is shown in Figure 6. The high-pressure area is schematically marked with a (+) sign. Figure 6 shows an isometric view of the improved transport concept. Free current approaches from the front face of the plate (11); left, right and rear 20 Fluid jets exiting from the edges (1) (8.9.19) around the plate (11) three-sided br fluid curtains (12,13,14) are formed in figures 7, 8, 9, 10, 11, 12. These fluid curtains (12,13,14) created allow the free stream to flow directly onto the plate (11) While allowing entry to the lower region, it exits via fluid curtains (12,13,14). It tries to block it. As a result, the flow velocity decreases in the lower region and here br 25 A stagnant or slowed flow region occurs. In this region, on top of the plate (11) According to this, a high static pressure is created, This high pressure is created on the lower surface of the plate (11) By acting, it produces an upward lifting force (lift) as shown in figures l-7,8,9,10,11,12. Specifically, under the target plate (7) which is surrounded on three sides by a fluid curtain (12,13,14). When the pressure reaches the maximum level, the front plate (6) 30 which has no shielding on the sides Below this, a lower pressure is created. This difference is shown as a small difference on the figure. It is expressed with plus (+) symbols in Figures 5, 6, and 9. 8 A sample BRS simulation of the invention was also performed: (Figure 7, Figure 8, Figure 9, Figure 10, Figure 5) Figures 11 and 12 are images taken from this simulation and support the discovery. Figure 7 shows a plane based on computational fluid dynamics (CFD) simulation. Spatial distribution of jet outlet channels (3,4,5) placed around plate (11) It is shown. The plate (11) has narrow openings (jet outlets) integrated on three sides. It is surrounded by environmental fluid curtains (12,13,14) via its channels (3,4,5). Figure 8. Fluid jets erupting from slits (8,9,10), free flow around plate (11). by forming fluid curtains that partially block and direct downwards (12,13,14) A stagnation zone is formed under the plate (11). The fluid flows in this region. As it slows down, the net k energy turns into static k pressure, so that the plate (11) under it The pressure level increases and an upward lifting force (1 ft) is created (Figures l-9, l-10, 15). Figure 11, Figure 12. The subject of the invention is the conveying force using a fluid curtain-based conveying system. To produce the plate (11), the surface of the plate does not necessarily have to be flat, different surfaces The same concept can be applied to profiles as well. The invention concerns a fluid curtain-based transport concept for both subsonic and supersonic applications. It can be used in high-speed regimes. There are no restrictions in terms of fluid type; air, water, oil, etc. are all acceptable. Fluid transport systems based on fluid barriers can be used as the subject of this invention. (The concept can be applied to machines operating in the side air, at sea, or using other fluids.) The fluid curtains (12,13,14) created around the plate (11) are 25 in the direction of the incoming flow. Depending on the context, it can be formed from different angles, and can be optimized to suit the project. 3. Fluidized curtains (12,13,14) can be on the sides and back as in the example application. It can be formed as three-sided flat curtains as shown in Figure 3. However, the concept is flat, circular. or it can be applied in other geometric forms. 30 The subject of the invention is a fluid curtain-based conveying system that only requires conveying force.

It can also be used for other purposes. 9 The subject of the invention is a fluid curtain-based conveying system with an applied surface area of ​​n,5 The shape can be changed according to system requirements.
