| 摘 要： | 为了对Laval喷管流场进行模拟时得到准确和高效的结果,文章采用数值模拟的方法,针对可压缩粘性流动的S-A,k-ε,k-ω等湍流模型在收敛速度、质量流量误差、马赫数的误差等多方面进行了比较。最终得出采用k-ω湍流模型对Laval喷管进行数值模拟是有效的结论。

| Abstract: | In order to get an accurate and high efficient result of the Laval nozzle flow field during simulating,by using the method of numerical simulation,in this paper turbulence models of compressible viscous flow S-A,k-ε,k-ω,are compared in convergence speed,qualitative flow error,Ma error,etc. We finally draw the conclusion that k-ω turbulence model in the numerical simulation of Laval Nozzle is most efficient. |
