英文摘要	In order to study the unsteady flow of solid-liquid twophase in rotor and stator cascades in centrifugal pump, two kinds of flow field are simulated, which are in a centrifugal pump with radial diffusers when the medium is clear water and solid-liquid, by combining the Large Eddy Simulation (LES) turbulence model and the Mixture multiphase model and using sliding mesh technology. The structure and evolution process of interior coherent vortex are studied contrastively. The evolution of vortexes on different positions is analyzed. The results show that: When the particle size is 0.01 mm, the particle density is 2650 kg/m3 and the concentration of the solid-phase is 10%, the influence of particles on the distribution of vorticity in pump is not obvious. However, it accelerates the dissipation of eddy and change the location and forms of vortex. In the same operating condition, the evolution processes of the vortex are different in different geometric positions.
