摘要 | Numerical calculation of the internal flow field in a double suction centrifugal pump was performed by commercial CFD software. The static pressures along circumferential and axial directions on impeller-volute coupling surface were calculated. By comparing the experimental results with numerical calculations, good agreement was obtained, the relative error is less than 5%, and the tendency of pressure distribution for impeller exit from numerical calculation is consistent with the experimental one. The radial force and its components were calculated with the outlet pressure method. The results show that the application of numerical model to calculate the radial force of the centrifugal pump has certain accuracy. At small flow condition, the radial force decreases with the increase of flow rate; near the designed flow rate condition, the radial force reaches the minimum; and at large flow condition, the radial force increases with the flow rate. |
