本文研究用时间稳定法求解高超声速三维化学非平衡流动简化ＮＳ方程，把整个非平衡流体动力学问题分裂为流体力学问题和化学问题。流体力学与化学问题之间的耦合通过迭代方式加以处理。考虑高温空气分解与电离，七个化学组元，并认为化学反应是以有限速率进行的．差分格式采用无自由参数的混合反扩散格式，激波及壁面处理应用特征线理论．对来流攻角为１０°，马赫数为２６，飞行高度为８５ｋｍ的钝锥体，给出了流场参数和物面加热率的数值计算结果．
In this paper, the time-stabilized method is used to solve the hypersonic three-dimensional chemical non-equilibrium flow simplified Navier-Stokes equations, which splits the entire non-equilibrium hydrodynamic problems into fluid mechanics problems and chemical problems. The coupling between fluid mechanics and chemical problems is handled iteratively. Consider the high temperature air decomposition and ionization, seven chemical elements, and that the chemical reaction is carried out at a finite rate. The differential format uses a hybrid anti-proliferation format with no free parameters, a shock wave and wall treatment application feature line theory. The results of numerical calculation of flow field parameters and surface heating rate are given for a blunt cone with a 10 ° attack angle, a Mach number of 26 and a flight height of 85 km.
