... and radial force in a low-specific-speed centrifugal pump by using the detached-eddy simulation method. We also performed a vibration displacement experiment on the shaft of the centrifugal pump. The vortex identification method was introduced to clarify the internal correlation between unsteady flow...

..., the backflow vortex cavitation, and the blade cavitation. These forms of cavitation are related to the inducer geometry, such as the hub shape studied by Mejri et al. [ 15 ] who found that inducers with conical hubs had better cavitation performances. These are also related to the blade number studied...
