| Abstract: | Considering the complexity of the flow state with high head,low capacity and long passage,the hydraulic design of low specific speed centrifugal pump impellers was based on similarity theory and its hydraulic performance is highly dependent on the model of impeller and experience of designer.A numerical method was put forward combining the advantages of similarity theory design and 2D theory design,adopting quasi-orthogonal method and Euler energy equation to calculate meridional velocity distribution,adjus... |
