| Abstract: | Taking mixed-flow pump as an investigation subject,a standard k-ε turbulence model and SIMPLE algorithm based on unstructured grid are applied to simulate numerically the interior flow field of mixed-pump by software CFD.The results indicates that the numerical simulation agrees with the experiment results,which reveals the main characteristics of the mixed-flow pump by analyzing the distribution of pressure and flow speed of mixed-flow pump,and provide the basis for the performance prediction and the optimization design of the mixed-flow pump. |
