This paper gives an overview of numerical flow control investigations for a high-lift airfoil. The flow around a real glider airfoil with a deflected camber flap at stall conditions was simulated with the Reynolds-averaged Navier-Stokes equations in combination with the LLR-k-o turbulence model. For this configuration flow separation can be delayed by periodic excitation through a slot close to the leading edge of the camber flap. By simulating different excitation positions, modes, frequencies, intensities and blow-out directions, a set of control parameters suitable for delaying separation and enhancing the lift could be identified.
