Abstract:

Among All Active flow control methods, EHD, MHD and EMHD are the only methods which operate on the basis of body force induction on flow field. The EHD plasma actuator is the proper method which has been used in various separation control applications recently. In this paper, we have studied the effects of different body forces which acting on different domain of flow field for separation control on NACA 0021. The airflow velocity is 35 m/s at a post-stall angle of attack of 23 degree. Three different domains have been used as body force field acting domains. The body forces are different in strength and direction. By simulations, body forces which give the best results in vanishing of separation are obtained. We have obtained the relation between electric and viscous forces ( b A number), and the relation between electric and inertia forces ( c D number) by using nondimensional analysis. It has been shown that Hartmann number and Stuart number in MHD play same role like b A and c D numbers in EHD. We have defined b A and c D numbers for EHD plasma actuators to show their efficiency in different flow control applications.
