Examples
Referring to fig. 1 and 2, the two-dimensional fluid device 001 according to the present embodiment includes a cover 010 and a rectifying cap 030.
Wherein the centre of the cover body 010 is provided with installation space, and the rectification cap 030 sets up in installation space's middle part, and the axle center of the cover body 010 coincides with the axle center of rectification cap 030, occupies the certain position of installation space through rectification cap 030.
The rectifying cap 030 occupies a certain position of the installation space, a rectifying space 050 is formed between the cover body 010 and the rectifying cap 030, and the rectifying space 050 is a space for fluid movement. The inner side of the radial section of the cover body 010 conforms to the equal-difference variable-diameter circular arc, that is, the radius change values of the circular arcs corresponding to the unit angle are equal. In this embodiment, the cover body 010 has a radial cross section in which the inner side is formed as a circle of an equal-difference variable-diameter arc having a radially overlapped portion, a small-diameter layer 013 close to the axial center and a large-diameter layer 015 away from the axial center are formed in the radially overlapped portion, and a gap between the small-diameter layer 013 and the large-diameter layer 015 forms the outlet 100 of the cover body 010. In this embodiment, the whole cover body 010 is a column, and one end of the cover body 010 is provided with a top opening 011, and the top opening 011 is used for fluid to enter or flow out.
The outside of the radial cross section of the rectifying cap 030 is circular, and specifically, the rectifying cap 030 may be hollow or solid. The rectifying cap 030 mainly functions to restrict the movement of fluid between the outer surface thereof and the inner surface of the cover body 010. It is only necessary to define the outer side of the radial section of the fairing cap 030. The diameter of the outer wall of the rectifying cap 030 changes continuously in the axial direction, that is, in the axial direction, the outer wall of the rectifying cap 030 does not exhibit a cliff.
Specifically, the diameter of the outer wall of the rectifying cap 030 gradually increases from the end close to the top opening 011 of the cover body 010 to the end away from the top opening 011 in the axial direction. After the fluid enters from the top opening 011, the rectification space 050 becomes smaller and smaller, and the continuity from one end close to the top opening 011 of the cover body 010 to one end far away from the top opening 011 becomes smaller, so that the fluid is gradually squeezed and rectified.
According to the principle of fluid mechanics, the fluid is compressed or expanded in volume under the influence of pressure changes, and the volume changes accord with the law that the force is sequentially conducted between adjacent media, so that the fluid has the law of moving from a high-pressure position to an adjacent low-pressure position. When there is a pressure difference between the external pressure and the inside of the device, the medium inside the cover body 010 moves from the high pressure position to the low pressure position, so as to form a flowing fluid.
The medium near the inner wall of the cover body 010 will naturally form a centrifugal spiral fluid 002 similar to the reducing circular arc, and the fluid at the center position will be driven into the centrifugal spiral fluid 002. After the fluid is rectified in the rectifying space 050, the fluid which forms a two-dimensional shape flows out from the outlet 100.
The outlet 100 is further provided with a deflector 110, one side of the deflector 110 is fixedly connected with the small-diameter layer 013, and the other side of the deflector 110 is fixedly connected with the large-diameter layer 015. The plane of the baffle 110 forms an acute angle with the radial direction of the cover body 010, so that the baffle 110 performs final rectification on the fluid about to flow out of the outlet 100, and the side of the baffle 110 close to the rectification space 050 directly bears the impact of the fluid, and therefore the included angle should be set to conform to the spiral degree of most of the fluid as much as possible. The guide vane 110 may serve to finally determine the moving direction of the fluid and also serve as a reinforcing means.
In this embodiment, the cover body 010 is columnar, and in other embodiments, the cover body 010 may be entirely bullet-shaped, cone-shaped, or in other shapes, but any radial cross section should conform to an equal-difference variable-diameter circular arc, and when the shape of the cover body 010 is changed, only the corresponding variable is correspondingly stacked and designed on the rectifying cap 030, and as long as the functional characteristic of the radial cross section of the rectifying space 050 is not affected, the principle of this embodiment is still satisfied, that is: as long as the rectification space 050 formed between the cover body 010 and the rectification cap 030 can enable the fluid to be gradually squeezed to form a spiral motion state, and then the fluid flows out from the outlet 100.
In this embodiment, the radial cross section of the cover body 010 is a circle of single-line equal-difference reducing circular arc, only one outlet 100 is provided, and the thickness h of the outlet 100 is the screw pitch of the equal-difference reducing circular arc. It should be noted that, since the material has a real thickness, in a real case, the real pitch should be h plus the thickness of the material. In other embodiments, the multi-line equal-difference reducing circular arcs may be combined, as shown in fig. 3, the two-line equal-difference reducing circular arcs are combined, and have two outlets 100.
The outlet 100 has a radial thickness h, the outlet 100 has a length L parallel to the axial direction of the cover body 010, the cover body 010 has an arc segment number n conforming to an equal-difference variable-diameter arc, the cover body 010 has a top opening 011, and the area of the top opening 011 is s conforming toWherein p is a positive number of a compression coefficient, and the coefficient is valued according to actual needs: when the p value is larger than 1, the fluid can be artificially compressed, and when the p value is smaller than 1, the flow can be enabledThe body obtains artificial inflation, and such design can adapt to the condition that the fluid must take place expansion or shrink because of the device internal and external pressure difference is great or temperature variation is great in some practical application scenarios, carries out the value to P as required and can change the pressure of fluid as far as possible, also can make the device itself have the function of compressing the fluid or supplying fluid shrink, inflation.
The radial section of the rectifying cap 030 has an area S' satisfying the formulaThe deflector cap 030 has a top end near the top opening 011 and L' is the distance from the radial cross section to the top end of the deflector cap 030. Therefore, the outer surface of the integral rectifying cap 030 is matched with a paraboloid formed by the rotation of the parabola along the central axis.
The utility model provides a two-dimensional fluidic device 001's overall principle does:
centrifugal spiral fluid 002 has a centrifugal force that tends to move centrifugally, but this also causes a reduction in pressure in its axial region, thereby counteracting the centrifugal tendency. The equal-difference reducing circular arc on the inner wall of the cover body 010 can form a smooth interface, and the equal-difference reducing circular arc is very fit with the centrifugal motion trend of the centrifugal spiral fluid 002. The rectifying cap 030 with the cross-sectional area equal-difference cone structure is used for uniformly extruding a low-pressure area occupying the axis area of the centrifugal spiral fluid 002, so that the pressure is balanced, the centrifugal motion trend is prevented from being offset, and the energy loss is further avoided.
Therefore, the cover body 010 and the rectifying cap 030 provided by the utility model are combined, and fluid in various forms can be better rectified into approximate two-dimensional forms. The conversion of two-dimensional fluids into three-dimensional fluids can also be achieved efficiently.
The utility model discloses can reach the characteristics of the slick and sly connection of different radius circular arcs according to the reducing circular arc, design a device that follows fluid motion law, the fluid of any motion form all can be rectified into centrifugal spiral motion form with the inner wall structure of even gradual change by its reducing circular arc cover body 010 when entering the device from the entry, promptly: the spiral fluid 002 is centrifuged. Centrifugal spiral fluid 002 has centrifugal force, makes its regional pressure intensity in axle center reduce, and sets up the cowling cap 030 at reducing circular arc cover body 010 axle center position be the cross-sectional area arithmetic cone, and it can be even gradual change crowd the space that occupies the central region to balanced pressure avoids centrifugal motion trend to be offset, and then avoids energy loss. The rectified centrifugal spiral fluid 002 exits from the outlet 100 by its own centrifugal force and moving speed, and the fluid is rectified to approximate a two-dimensional shape. The baffles 110 of the outlet 100 serve to further straighten and ultimately orient the fluid movement and also serve as stiffening means.
The utility model provides a two-dimensional fluidic device 001 has two kinds of application methods:
1. a medium is introduced from the top opening 011, and rectification is performed through the rectification space 050 to rectify the three-dimensional motion form into a two-dimensional motion form.
The application field is as follows: such as the control and utilization of air in the aviation field, the control and utilization of air in the air conditioning field, the control and utilization of water flow in the marine diving field, the control and utilization of water flow in the water conservancy and hydropower field, the control and utilization of microscopic particles in the scientific research field, the control and utilization of gas, liquid, particles and other fine media in the industrial field, the design of a turbocharger, the manufacture of graphene, or the rectification of a three-dimensional form medium into an approximately two-dimensional form, or the use in other fields.
2. The medium is introduced from the outlet 100 and exits from the top opening 011 along the rectifying space 050 rectifying the two-dimensional motion pattern of the fluid into a three-dimensional motion pattern. The device can be used for driving a propeller, a turbine, a fan and the like, further driving an energy conversion device to utilize kinetic energy, or performing three-dimensional integration on a medium similar to a two-dimensional form. The utility model discloses can increase substantially the efficiency of equipment such as hydraulic turbine, steam turbine, aerogenerator, or be used for other fields.

In some practical applications, the fluid is generated by driving a propeller, a turbine, a fan, etc. through a power device, so as to drive a medium to form a fluid, where the fluid is in a spiral axial composite motion form, and then the fluid needs to be rectified into a pure axial motion or a pure spiral motion, and then the fluid is compressed into a two-dimensional form by using a second set of device. The process changes the moving direction, speed and pressure of the fluid for many times, the moving track of the fluid is also changed continuously, and the energy loss is large. The method of producing fluid by using a piston-like device requires a great change in the pressure of the fluid, which is discontinuous and uneven, and the pressure of the fluid fluctuates greatly, resulting in a remarkable energy loss.
