چکیده انگلیسی

With the rapid development of the Computational Fluid Dynamics (CFD), it is in a high demand and still remains unresolved to compute hypersonic heating accurately. In the past years, many researchers tried to solve this problem by studying the upwind scheme's choice. However, most of them just focused on the following two aspects: the scheme's level of robustness against the shock anomaly and the scheme's resolution in capturing discontinuity. Few people relate this problem to the scheme's level of accuracy at low speeds. In this paper, we conduct a systematic study on this issue. Results in our test cases show that a high level of accuracy at low speeds is beneficial to the hypersonic heating computations. Also, the AUSMPWM scheme performs well in hypersonic heating computations.
