Low-frequency unsteadiness in hypersonic swept shock wave-boundary layer interactions

Abstract
We carry out a numerical study of swept shock wave/turbulent boundary layer interaction (SBLI) in the hypersonic regime, where a crossflow velocity component is added to the incoming flow to mimic three-dimensional interactions with cylindrical symmetry. The spatiotemporal dynamics of wall pressure well conform with the previously introduced formula for swept supersonic interactions, extending the validity of the model to SBLIs in the hypersonic regime.
