The flow of dilute sandy water (sand carrying capacity less than 1.0kg/m3 ) in plane cascade is numerically solved. The collision efficiency is defined. The influence of the Reynolds number based on the characteristic length of the cascade, the angle of attack and the sand diameter on the collision efficiency are discussed. The trajectories and impinging action of sand particles moving in plane cascade flow are calculated by including the effects of the wall, the boundary layer, the wake, the sand particle size and the collision of the sand particle-wall.
