Description

technical field [0001] The invention relates to a generator, in particular to a vertical vortex 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. Vortex generators are one of the effective methods to overcome boundary layer separation. The vortex generators used to control flow separation mostly require mechanical structural parts. Although they can play a role in controlling separation in the boundary layer flow, when the boundary layer does not separate, it will have a negative impact on the flow. Other devices that can control flow separation often require additional air sources, and there are many components, complex structures, difficult processing or large processing volume. In production, the requirement of blending m...

Problems solved by technology

[0007] The purpose of the present invention is to aim at the relatively complex structure of some existing generators capable of forming eddy currents, which cannot directly generate eddy currents on plane or smooth object surfaces, although the vortex generators that can control the boundary layer flow can achieve the purpose , but it also has negative effects on the non-separated flow. A vertical vortex generator with a relatively simple structure that can directly generate vertical vortices on the surface of a plane or smooth object is provided.
