介绍了小马赫数下弱可压缩流体流动的模型,对该模型的数值求解方法也作了较为详尽的叙 述。讨论了紊流模型模拟涡流的方法。简要介绍了水力机械内部流场的计算实例。

In the paper,a weakly compressible flow model for small Mach number is introduce d;the method of mumerical solution is given in detail;the method for simulating vortex flow is discussed;and calculation illustrations on flow fields inside hyd raulic machineries are briefly represented.
