Abstract
The performance of an axial-flow pump stage and its interior flow field are studied numerically. The calculated region is from the inlet of pump stage to the outlet of thruster, including impeller, stator and spout. The region is spitted by structure grid, and governing equations are solved by NUMECA software. The flow fields are calculated by the method of time-marching scheme. The performances of flow rate-head and flow rate-efficiency of pump stage are predicted according to the computation results. The prediction results are compared with experimental ones, and calculated results are preferably consistent with the experimental data. It shows that this calculation method has higher creditability and computational accuracy. Furthermore, the performance of the pump stage is analyzed based on the computational results.
