Abstract

The numerical investigations described in the present paper deal with active flow control for a 2D, 2-element high-lift airfoil under low speed wind tunnel conditions. Here, the aim of the flow control application is the transport of fluid-momentum from the outer part of the boundary layer towards the wall to actively reduce or eliminate the large flow separation on the flap. The URANS simulations carried out in this study focus on the variation of the streamwise actuator-slot width and the actuation direction, and their potential to suppress or delay separation. Different slot-exit settings coupled with a constant frequency, duty cycle, and mass flow are discussed regarding their impact on the local flow.
