On the investigation of oblique shock‐wave/turbulent boundary‐layer interactions with a high‐order discontinuous Galerkin method

Shock-wave/turbulent boundary-layer interactions are still a challenge for numerical simulation. The shock capturing needs dissipation to avoid spurious oscillations while turbulence will be falsified by introducing dissipation. Especially, an accurate prediction of quantities such as the skin-friction coefficient inside interaction area wave and turbulent flow is critical point. In this article, we investigate wall-resolved large eddy simulation oblique shock-wave/turbulent high-order discontinuous Galerkin scheme. scheme handles very well. shock-capturing confined near region switching locally finite volume second-order TVD on subcells.
