In view of the problem of deterioration of aerodynamic performance of the airfoil due to dynamic stall,the miniaturized actuation power supply and dielectric barrier discharge plasma actuator are employed to conduct experimental study on the plasma flow control of airfoil dynamic stall by means of dynamic pressure measurement and external trigger Particle Image Velocimetry(PIV).It is shown that the aerodynamic actuation of dielectric barrier discharge plasma can effectively control the airfoil dynamic stall...
