Abstract: In this study, a double volute centrifugal pump with relative low efficiency and high vibration is redesigned to improve the efficiency and reduce the unsteady radial forces with the aid of unsteady computational fluid ...

Abstract: In the previous paper, the high potential of the spectral correlation to identify cavity type has been demonstrated. This paper dedicates its efforts to cavity development evaluation and shows how the proposed modulation ...

Abstract: It has been confirmed that the passive obstacles would substantially depress the leading-edge cavitation in a waterjet pump. Combined with the experiments and numerical simulations, this work revisits blade cavitation ...
