摘要
本文从轴对称热化学非平衡Ｎ－ Ｓ方程出发，采用双温度、十一组元反应气体模型，利用隐式ＮＮＤ有限差分格式和时间预处理技术数值求解了ＦＩＲＥＩＩ飞船热化学非平衡流场。文中同时给出了七组元模型的计算结果，并进行了结果比较。
The symmetric Thermochemical Nonequilibrium flow is simulated numerically. The full Navier Stokes equations are taken as the governing equations. The two temperature and eleven species gas model is considered. NND scheme for shock capture and time preconditional metrix technique is used for numerical solution of thermochemical nonequilibrium flowfield over FIREII capsule. The result of seven species is also given for contrast.
