本文成功地将二阶迎风 TVD 数值格式运用到弱电离、化学非平衡斜激波反射流场的数值计算中。气体力学方程与组元质量守恒方程组全耦合求解是目前非平衡流场数值计算中的新方向,文中详细给出了气体力学方程和组元质量守恒方程组全耦合求解过程,最后给出了三种不同情况斜激波反射流场数值结果并进行了详细讨论,本文所得结果与文献〔4〕提供的实验结果和文献〔1〕提供的数值结果相符合。
In this paper, we successfully apply the second-order upwind TVD numerical scheme to the numerical calculation of weakly ionized and chemically unbalanced oblique shock reflections. The full coupling solution of gas-mechanical equations and element-mass conservation equations is the new direction in numerical calculation of non-equilibrium flow fields. The full coupled solution of gas-mechanical equations and element-mass conservation equations is given in detail. Finally, Three different cases of oblique shock reflection flow numerical results and discussed in detail, the results obtained in this paper [4] and the experimental results provided in [1] the numerical results are consistent.
