| 摘 要： | 采用单、双温度模型两种粘性激波层方程组对弹头驻点区非平衡流场作了数值模拟。计算结果表明，在算例条件下热非平衡与化学非平衡的耦合效应对壁面热流和电子密度有明显影响。文中给出了完全催化壁和非催化壁两种情况下以及采用不同振动松弛时间公式时上述影响的变化规律。

| Abstract: | The numerical solutions of VSL equation sets in one-temperature and two-temperature cases are obtained for flows in the stagnation region of a hypervelocity blunt body.The results indicated that there are remarkable effects of coupled thermal and chemical nonequilibrium on the wall heat transfer and electron number density in the flowsi and the difference between the results for two different expressions of vibrational re1axation time are also notable. |
