PIV investigation on flow induced by plasma aerodynamic actuation

PIV investigation on flow induced by plasma aerodynamic actuation was presented in the paper to reveal the operation mechanism between plasma aerodynamic actuation and airflow. The experimental results show that the flow induced by millisecond and microsecond plasma aerodynamic actuation come out as starting vortex and wall jet. The maximal induced velocity is about 3m/s when the actuation voltage is 12kV. The higher the voltage is, the stronger the starting vortex and the wall jet. The intensity and the influence of the pulse actuation are higher than that of the steady actuation. The results are instructional for increasing the ability of plasma flow control.
