The aerodynamic performance of TAU0015 airfoil was investigated with synthetic jet control method. The simplified mathematical model of the active flow control was established with unsteady velocity boundary condition at the specific location of airfoil surface. The aerodynamic performance was simulated with synthetic jet and the efficiency of jet momentum coefficient was conducted. The result shows that the flow control model could perform the minor jet flow characteristics and higher jet momentum coefficient result better control efficiency.

This paper describes the application of active flow control for the NLR7301 supercritical airfoil/flap configuration at Re = 2.51x106. A parametric analysis is conducted to investigate the effects of jet parameters (jet direction, jet location and momentum coefficient) on the aerodynamic performance of a multi-element airfoil. The results indicate that flow separation is delayed and efficiency of jet can be improved with specific momentum coefficient (the best lift-drag ratio at Cμ=0.16) and jet angle (16°) when the jet is located near the separation point of the airfoil.
