Induction of Boundary Layer by Plasma Actuator

Plasma inducing the low flow velocity boundary layer was investigated,and the affection of different plasma actuator excitation intensity,size and main flow velocity to the flow boundary layer was analyzed,in which the plasma was produced by a high-voltage RF(radio frequence) actuator.Through the simulation and analysis,it is found that the flow boundary is changed greatly by the induction of plasma actuator,the plasma actuator can produce significant accelerating inducing flow on the main flow.So the plasma technology can be used to control flow,such as control flow separation of the airplane airfoil or aeroengine vane,and can be used to improve the off-design performance of airplane and aeroengine or scramjet.
