Abstract
We investigate the interaction of an oblique shock generated by a pitching wedge with a turbulent boundary-layer at a free-stream Mach number of Ma = 3:0 and a Reynolds number based on the incoming boundary-layer thickness of Re_delta0,I = 205 x 10^3. Large-eddy simulations (LES) are performed for two configurations, that differ in the treatment of the wind-tunnel wall and shock generator movement within the experiment: A fixed panel with a static shock generator that deflects the flow by Theta = 20°, and the transient interaction of a pitching shock generator with an elastic panel. Besides mean and instantaneous flow quantities, we investigate unsteady aspects of the interaction region by means of wall-pressure spectra and provide comparison with experimental data whenever possible.
