| 摘 要： | 利用计算流体力学(CFD)的后处理技术分析喷水推进泵的流动特点,发现泵定子设计的不足。通过改变泵转子和定子的轴向间距,分别分析前置定子和后置定子与转子的相互作用,得到了转子和前、后置定子的最佳轴向间距。

| Abstract: | The computational fluid dynamics(CFD) was applied in a marine water-jet pump numerical simulation to gain the curves of head,power,and efficiency of the pump.The fault of design was gotten by analyzing characteristic fluid flow region of water-jet pump.The interaction between the impeller and the rotor was studied with CFD technology through changing the axis length of them,and the best axis lengths were received. |
