An effective flux scheme for hypersonic heating prediction of re-entry vehicles

In this article, an effective computational method called TVM is proposed for the hypersonic heating prediction of the re-entry vehicles. Aimming at resolving the boundary layer accurately, the method adopted the splitting manner of the Toro and Vzquez's splitting procedure with an improved low-dissipation modification. Also, the method is robust against the shock anomaly in hypersonic flows. The detailed construction of the scheme is presented and a series of testcases are conducted to validate the performance of the newly developed scheme. Finally, the scheme is applied to the simulation of the hypersonic re-entry vehicles. Numerical results show its high performance in the prediction of the re-entry vehicles hypersonic heating load compared to the traditional methods.
