Some influence factors in aerodynamic heat transfer numerical simulation of jet-interaction flow

  • 摘要: 工程上对喷流气动热进行近似计算时,常常对真实的全化学反应流近似处理,这时需要了解喷流气体和喷管外形的近似方法对计算结果的影响规律。采用数值试验对比分析的方法,探讨了近似计算的2个影响因素:其一是使用量热完全的空气喷流近似燃气喷流进行数值模拟时,喷管几何形状对热流分布的影响;其二是使用空气喷流近似燃气喷流进行数值模拟的方法,分析不同的喷流热力学参数匹配方法对喷流形态及热流分布的影响。通过对不同方法进行对比计算,揭示了各个方法对喷流干扰气动热计算的影响规律,可以用于指导工程分析。
