摘要：

Synthetic jet, which is one of the methods for active flow control, has been caused extensive concerns in the last few years. In this paper, aimed at increasing flying lift, the flow field control effect on the micro aerial vehicle (MAV) in a viscous flow under the low-Reynolds number with a synthetic jet located at the surface of NACA0015 airfoil was numerically studied. Moreover, the Jameson's central finite volume method was adopted in the spatial differentiation of the control equations, while the dual time step method in time marching and the implicit LU-SSOR scheme in the sub-iteration. The computational results indicate that the control technique of synthetic jet has influence on controlling the flow separation in a large angle of attack and improving the aerodynamic performance of the airfoil, and also have an effect on increasing the lift and decreasing the drag.
