  • 摘要:

    高超声速气动加热严重,考虑热化学非平衡对气动热环境影响,可以为热防护系统设计提供有效保障。采用Park和Gupta热化学非平衡模型,数值计算研究5组元(N2,O2,N,O,NO),17组化学反应的热化学非平衡效应对高超声速飞行器气动热环境影响,并与完全气体和热化学平衡模型进行对比分析。热化学非平衡模型流场温度及激波距离均比完全气体模型小。激波后气体密度因离解、化学反应而增大,且气体密度越大,激波距离越小,热化学平衡模型激波距离最小。完全气体和热化学平衡模型热流载荷计算值均比实验值偏大。Park和Gupta热化学非平衡模型数值计算激波距离及气动力载荷差别小。Park模型热流载荷计算值偏大,Gupta模型与实验结果相符,它可对气动热环境可靠预测。
