For more effectively utilizing state of the plasma flow characteristics, to control separation of boundary layer from the subsonic to supersonic, the vortex flow, viscous coupling including shock induced separation, to improve combustion stability and efficiency, thereby minimizing the parasitic resistance and controlling separation bubble issue effectively. Therefore, the main research focus of this paper will be divided into two parts. The first part, the experimental design and measurement will be implemented under atmosphere temperature and pressure conditions, including the actuator for driving the high voltage AC dielectric plasma between the geometric parameters and the actuating voltage and the relationship between the discharge characteristics of actuator. The second part, we apply the finite volume method to solve the Navier-Stokes equations, and combines the modified physical model of electrostatic field. Through the applied AC voltage and charge density equation for solving Maxwell's equations and the way of obtaining an electric field, investigate the dielectric discharge flow affecting the acceleration effects of normal atmospheric pressure plasma and its impact on the boundary layer flows of thin plate. According to the mentioned above, considering the number of different geometric parameters and different actuator free flow conditions, the impact of physical parameters, for instance, electric potential, electric density and body forces which generated by plasma actuator in computational model, and their further interactions with thin plate boundary layer flow, and then the induced velocity field are discussed in detail.
