| 摘要: |
| 本文从轴对称热化学非平衡N-S方程出发, 利用时间相关法, 采用双温度、七组元反应气体模型, 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, 得到了较为准确的结果, 并分析了热力非平衡对流场的影响。 |

| Abstract: |
| The symmetric thermochemical nonequilibrium flow is simulated numerically. The full Navier-Stokes equations are taken as the governing equations. The time-dependent analysis is used. The two-temperature and seven species gas model is adopted. NND scheme for shock capture and time preconditional metrix technique are used for numerical solution. The influence of thermochemical nonequilibrium on flow field is analysed. |
