Abstract

The objective of this paper is to evaluate, via numerical simulation, the feasibility of weakening the shock wave(s) and reducing the pockets of supersonic regions on airfoils/wings in transonic flight using active flow control (AFC) devices such as synthetic jet actuators (SJA), and thereby achieving the desired changes in aerodynamic forces and moments. Most importantly, it is shown that both the enhancement in lift and reduction in drag can be achieved by using multiple synthetic jet actuators suitably placed on the upper surface of the airfoil.
