International Journal of Aerospace Engineering, Volume 2023, Issue 1, 2023., 2023 This study investigated the thermal protection performance of an active jet thermal protection system (PRsAJ‐TPS) based on a new jet design parameter PRs for hypersonic flight vehicles (HFVs). The new parameter PRs is defined as the relationship between the jet flow total pressure and the free flow total pressure behind the outer bow shock.

International Journal for Numerical Methods in Fluids, Volume 94, Issue 8, Page 1331-1357, August 2022., 2022 (1) We firstly investigate the accuracy and efficiency of the high‐order discontinuous Galerkin spectral element method for the implicit large eddy simulation in oblique shock‐wave/turbulent boundary‐layer interaction. (2) We propose a new idea of improving the shock‐capturing capability of the classic Jameson shock indicator by employing a spatial ...
