000014483 520__ $$2eng$$aWe investigate the interaction of an oblique shock-wave with a turbulent boundary-layer at a free-stream Mach number of W230 and a Reynolds number based on the incoming momentum thickness of R690 2 14000 by means of wall-resolved large-eddy simulations (LES). Previous numerical studies (both LES or DNS) mainly focused on weak interactions at rather low Reynolds numbers up to around R650 m 50 - 103. We extend the numerical database to strong interactions with massive mean-flow separation at a Reynolds number of R650 m 203 - 103. A direct comparison of simulation and experiment is given in terms of mean and unsteady wall-pressure measurements. The low-frequency unsteadiness is studied in more detail by linear spectral analysis (power spectral density, coherence and phase), as well as modal decomposition techniques (dynamic mode decomposition in 2D and 3D).
