Abstract: Currently, sediment abrasion is becoming more and more serious in hydraulic machinery. In this paper, the internal flow field of solid-liquid two phase was analyzed. In order to improve the uniformity of solid distribution on the surface of rotating disk, the solid particle diameter and inlet concentration need be reduced. With the increasing of the particle diameter and concentration, the difference of solid volume fraction increases between the rotation center and edge of disk. Particles’ velocity of impact the disk’s surface linearly increases along the increasing disk radius. The impact velocity at the outer edge of the disk is maximal, reaching over 40m/s. The change of impact velocity at each radius is not obvious with the variety of particle diameter.
