Abstract�� The flow induced by plasma actuator in two dimensional incompressible flow was simulated based on a phenomenological model, which was realized by adding the body force source term to the Navier-Stokes equations. The numerical results present that there is a wall jet formed downstream of the plasma actuator. The velocity profiles at different streamwise stations, the variation of the maximum velocity and the width variation of the wall jet are quit similar to the traditional laminar jet(wall jet or two dimensional slot jet), which indicates that the effect of the plasma actuator on the ambient neutral flow can be regarded as potential flow interaction. At last, the blowing momentum coefficient of the wall jet induced by the plasma actuator was obtained by integration, which was negligible compared with that of the traditional blowing flow control method. So the plasma actuator flow control method just can be applied in low speed flow at present.
