Embodiment Construction
[0034] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.
[0035] The present invention proposes a plasma vortex generator, which is realized through a specific layout of a plasma actuator on a control body such as a flat plate or an airfoil. One or more groups of plasma exciters are attached near the front edge of the separation area near the surface of the control body such as the wing or flat plate. The wall jet has a certain deflection angle with the direction of the free flow, so that the interaction produces a flow direction vortex, which strengthens the momentum in the boundary layer and achieves the purpose of inhibiting or delaying the flow separation. The wind tunnel flow display experiment shows that the vortex generator based on the asymmetric dielectric barrier discharge plasma exciter proposed by the present invention can generate a flow direction vortex, and this flow direction vortex has a str...
