该文在归纳、总结、分析以往火箭燃气射流流场数值模拟的基础上，结合含有限速率化学反应火箭燃气射流流场的特有规律，利用推导的ＴＶＤ组合数值模拟算子，对某火箭燃气射流流场进行了数值计算。由于含化学反应流体的流动和单一组分混合流流动之间存在着较大的差异，特别是化学反应的存在在一定程度上影响了系统能量的改变，进而改变整个流场中的压力和温度分布，同时化学反应和激波之间的相互增强作用引发了流场中的异常压力和温度，结合数值模拟的结果，分析了产生这些现象的原因，并且和以往的计算结果进行了对比。
Based on the numerical simulation of the rocket gas jet flow field and the unique law of the gas jet flow field containing the rocket of limited rate chemical reaction, this paper makes use of the TVD combinatorial numerical simulation operator to calculate the rocket gas jet The flow field is numerically calculated. Because there is a big difference between the flow of chemical reaction fluid and the flow of single component mixed flow, especially the existence of chemical reaction affects the change of system energy to a certain extent, and then changes the pressure and temperature in the whole flow field Distribution, and the interaction between chemical reaction and shock wave triggers abnormal pressure and temperature in the flow field. The causes of these phenomena are analyzed in combination with the numerical simulation results, and the results are compared with the previous results.
