    Abstract

    Dielectric barrier discharge (DBD) plasma actuators have been used worldwide for aerodynamic flow-control. It is known that the effect of DBD is to produce a local body force within the boundary layer, which produces a wall jet. An analytical work has been carried out using the classical triple deck theory for subsonic flows to understand the flow dynamics with the local body force within the boundary layer. The results predict suction upstream of the disturbance (body force) and pumping downstream, which are in qualitative agreement with experiments conducted at LHSR, IISc.
