| 摘 要： | 高温非平衡化学反应对高超声速再入飞行器绕流流场的气动热特性有较大影响.通过采用有限体积NND(Non-oscillatory, containing No free parameters and Dissipative scheme)格式求解三维N-S方程,分别计算了小攻角条件下球锥的完全气体粘性流场和化学反应非平衡气体流场.比较并分析了化学非平衡作用对三维高超声速钝头体绕流流场的影响.所得结果与国外文献结果符合的较好,证明了计算方法与程序的有效性和实用性.

| Abstract: | High temperature chemical non equilibrium phenomena have a great effect on the flow field around a reentry vehicle. A three dimensional Navier Stokes equations were solved by implicit finite volume NND scheme. Both ideal gas viscous flow and chemical non equilibrium flow were calculated for a sphere cone at a small attack angle. The results of the two flows were compared and the effect of chemical non equilibrium was analyzed. The result is in good agreement with the reference paper. That proves that our method and programs are effective and practical. |
