Quantified insights into the effect of particle-vortex interaction on the hydraulic performance and erosion behavior in semi-open centrifugal pump

1.Under solid-liquid two-phase conditions, the structures of tip-leakage vortex, separation vortex, and passage vortex resemble those under clear water conditions. 2.Pressure pulsation in the semi-open centrifugal pump is significantly influenced by leakage vortex and particle migration is clarified. 3.The distribution of particles in the impeller under different Stokes numbers is revealed. 4.Distribution of erosion areas in the impeller under different Stokes numbers.
