Abstract
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.
