| Abstract: | In this article, numerical simulation of the interior flow of roto-jet pump is carried through, and the distribution rules of the pump internal turbulence flow are calculated. The computation results and experimental results are contrasted and analyzed. The research is important for understanding the interior flow status of roto-jet pump; enhancing the roto-jet pump efficiency, especially the influences of the manifold geometric parameters of impeller and collecting tube on pump performances; and provide valuable reference information for improving hydraulic design of roto-jet pump. |
