Abstract

The numerical investigations described in the present paper deal with active flow separation control for a 2D, 2-element high-lift airfoil. Here, the aim of the flow control application is to actively reduce or eliminate a large flow separation on the flap by a periodic excitation mechanism, known as pulsed blowing. This study explores the resulting effects of the flow control application on the global aerodynamic coefficients and, beyond this, by the analysis of the resulting loads variation by specific actuation parameters. For enabling the extrapolation towards flight Reynolds numbers the URANS computations are addressed at both low speed atmospheric windtunnel conditions (Re≈2x10^6.) as well as for higher Reynolds number comparable to flight conditions (Re≈7x10^6).
