Calculation of unsteady flow for interaction between rotating impeller and vaned diffuser 旋转叶轮和叶片扩压器耦合的非定常流动计算
2.
The results also display the impeller ' s good hydraulic properties and the vaned diffuser ' s imperfect hydraulic properties and low efficiency 计算结果还显示：潜油泵叶轮有较好的水力性能，而潜油泵导轮的水力性能是不完善的，效率较低。
3.
The internal flow field in submersible centrifugal pump is researched based on cfd , and numeric results of the impeller and vaned diffuser trader three different operating conditions are discussed and analysed 摘要采用cfd方法研究了潜油离心泵的内部流场，讨论分析了3种不同工况下叶轮和导轮的数值计算结果。
