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速燃烧室的冷态掺混粘性层流流动进行数值计算,采用MacCormack两步显式格式分析一股音速来流在两股超音速气流间掺混的流动特征,并用代数法生成计算网格。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。 By solving the complete two-dimensional Navier-Stokes equations, the cold mixed viscous laminar flow in a supersonic combustor of a ramjet / twin-combustor ramjet engine is numerically calculated and analyzed using MacCormack two-step explicit format Flows are mixed with flow characteristics between two supersonic flows and generated by the algebraic method. The results of three sets of examples given are compared with the experimental results in [1]. The results are satisfactory.
