Abstract

Based on the three dimensional geometry of the prototype design of a mixed flow pump, a numerical flow simulation and analytic platform based on commercial CFD software NUMECA was established to simulate the three-dimensional flows in the pumps. The pump volute with scroll-type and different cross-sections were studied. The key sources of the flow losses were analyzed and detailed structural modifications were proposed in this paper. Final results indicate that the efficiency can be increased by 4%.
