| 摘 要： | 通过求解完全的二维Ｎ－Ｓ方程组，对亚燃／超燃双燃烧室冲压发动机超音燃烧室的冷态掺混合性层流流动进行数值计算，采用ＭａｃＣｏｒｍａｃｋ两步显式格式分析一般音速来在股超音速气流间掺混的流动特征，并用代数法生成计算网络。给出的三组算例与文献（１）的实验结果进行对比，结果令人满意。

| Abstract: | The flowfield characteristics created by a sonic jet flow between two supersonic streams were investigated theoritically by solving full 2-D N-S equations. A computer program is developed to analyse viscous flowfield of cold mixing of a sonic jet flow with two supersonic streams by using MacCormack explicit scheme. Algebraical method is used in this study to generate computational grids. The agreement of computation with experimental results of reference [1] is rather satisfactory. |
