Numerical Investigation of Flow Control Over an Airfoil

The synthetic jet is applied over an airfoil to control the flow separation. Response Surface Methodology is employed for the optimization of synthetic jet parameters at various angles of attack. The synthetic jet parameters; the jet velocity, the jet location, the jet angle and the jet frequency are optimized to maximize the lift to drag ratio. The jet power coefficient is kept constant in the optimization. The lift to drag ratio increased significantly especially at post stall angles of attack.
