Plane rotational flow generator

Abstract

The invention relates to a plane rotational flow generator which belongs to a generator, in particular to a plane rotational flow generator which has simpler structure and can form rotational flows parallel to the plane or an article surface. The plane rotational flow generator is provided with a base plate and an alternating current power supply, at least four upper surface and lower surface electrodes are respectively covered on the upper surface and the lower surface of the base plate, the four upper surface and lower surface electrodes are all arc-shaped electrodes which are bent along a same direction, and the four upper surface and lower surface electrodes are pairwise and equidistantly distributed in an interlaced radiation shape along a circumference. Furthermore, the upper surface electrodes are electrically connected with each other, the lower surface electrodes are electrically connected with each other, each upper surface electrode and each lower surface electrode are respectively and electrically connected with two output ends of the alternating current power supply, and the lower surface of the base plate and the lower surface electrodes are respectively provide withelectrical medium material covering layers.

Description

technical field [0001] The invention relates to a generator, in particular to a plane swirl generator. Background technique [0002] The control of boundary layer separation is an important part of flow control. There are many methods. The main guiding idea is to increase the kinetic energy of the fluid in the boundary layer and improve its ability to resist separation to inhibit separation. Jets, vortex generators, etc. are effective methods to overcome boundary layer separation. However, most jets require additional air sources, and there are many components, complex structures, difficult processing or large processing volume. However, vortex generators often require mechanical structural parts, which can negatively affect the flow when the boundary layer does not separate. In production, the requirement of blending materials is often encountered, and the existing methods often require mechanisms and power with complex structures.

Problems solved by technology

[0007] The purpose of the present invention is to solve the complex structures of some existing generating devices capable of forming swirling flow, which cannot form swirling flows parallel to planes or object surfaces, but the vortex generators that can control the boundary layer flow It can achieve the purpose, but it also has negative effects on the non-separated flow. A planar swirl generator with a relatively simple structure that can form swirl parallel to the plane or the surface of the object is provided.
