摘要
采用显式的TVDMacCormack格式，并结合Baldwin－Lomax的代数湍流模型和低雷诺数两方程k－ε模型分别求解了喷管内横流流场的二维N－S方程，得到了与理论分析结果相近似的流场结构图谱，并对代数湍流模型和两方程模型得到的结果进行了比较，表明运用两方程模型所得到的结果稍好于代数模型。
A time-split explicit TVD MacCormack scheme is used to solve the two-dimensionalN-S equations of cross-flow in rocket motor nozzle. Both the algebraic turbulence model of Baldwinand Lomax and the low Reynold number two-equation k-ε turbulence model of Lam and Bremhorstare used in this procedure. The results are compared with each rother and show that the k-ε model cangive slightly better solutions than the algebraic one.
