Effects of cutting the blade on the performance and pressure pulsation of a centrifugal pump

open access: yesEnergy Science & Engineering, 2020
To solve the severe flow‐induced vibration during the pump operation, the impeller cut is a reasonable and operable approach. In the present study, effects of cutting the blade on the pump performance, especially for pressure pulsations, are conducted by
