Experiments on NACA0015 airfoil stalling separation control based on multiphase plasma aerodynamic actuation were performed in the paper.The effects of the plasma actuation voltage amplitude

phase

input waveform and duty cycle on the lift and drag of the airfoil were examined specifically.The results show that

when the Reynolds number is 4.9 ×105

multiphase plasma aerodynamic actuation can suppress flow separation very well.The critical stalling attack angle of NACA0015 airfoil can increase by 2°.The flow suppression effect is not sensitive to phase difference.The separated flow can be suppressed when the voltage amplitude and duty cycle reach their threshold values.Once the separated flow is suppressed

the actuation voltage magnitude maintaining flow attachment could be reduced significantly.The research can lay a foundation for the mechanism of multiphase plasma flow control.
