OBLIQUE COLLISIONS OF NON-ROTATING SPHERICAL PARTICLES WITH A WALL
Chára Z., Vlasák P., Kysela B.
pages 228 - 234, full text

In the present paper non-rotating particle-wall collisions were experimentally investigated. By means of the PIV method a velocity field around falling spheres was analyzed. It was shown that the wake behind the particle which approached a bed in non-normal direction was asymmetrical and after the impact the wake passed the particle only along one side. This non-symmetrical velocity field resulted in additional forces which pushed the particle to an opposite direction than was the direction of the particle motion just after the impact.
