摘要/Abstract

摘要： 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,文中详细地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]由I.I.Glass提供的实验结果和文献[1]由H.M.Glaz提供的数值结果相符合。

关键词: 非平衡流场, 斜激波反射, 迎风TVD格式

Abstract: In this paper several planar oblique shock reflection in weakly ionizing,chemically relaxing gas flow have been successfully simulated using a second-order upwind Total Variation Diminishing(TVD) scheme. In present nonequilibrium gas flow calculations the gas-dynamics and species-continuity equations are solved by fully coupling manner,and the fully coupling procedure is described in detail.Numerical solutions are presented with detailed discussion for three examples of oblique shock wave reflection.The numerical results obtained here agree well with the experiments in Refe.[4] by I.I.Glass and calculation results in Refe.[1] H.M.Glaz.

Key words: nonequilibrium flow, oblique shock wave reflection, upwind TVD scheme
