| Abstract: | The performance curves of self-priming vortex pump （25WZ1-12） were obtained through the test experiment.Based on the Reynolds averaged Navier-Stokes equations （RANS） and k-ω two-equation turbulence model,the interior flow field in the self-priming vortex pump were numerically simulated.Through the analysis and comparison between results of experiment and simulation,the formation of suction and head principles were explained.The investigation also showed the cavitation performance and self-priming process of the self-priming vortex pump. |
