ABSTRACT
This study indicates a numerical study on the applicability of DBD plasma actuator in the manipulation of boundary layer. A flat plate has been numerically simulated in this work. Asymmetric electrodes with a dielectric material in the space between, which are comprised of a Dielectric Barrier Discharge (DBD) is considered just at the edge of the flat plate. Lumped Circuit Element Electro-Static Model is applied to simulate the effect of the actuator. The flat plate was considered with no initial flow as the inlet condition. So, the results demonstrate just the impact of the DBD plasma body force on the fluid motion. Finally, as the main result of the present study, the separation of the quiescent flow with the viscous region is determined and also the flow suction by such an actuator is identified. The configuration of the DBD plasma actuator is set to be 10 KHz for the applied voltage frequency, Kapton as the dielectric and various peak voltage amplitudes.
