EFFECTS OF IMPACT VELOCITY AND ANGLE ON COLLISION

Abstract

In this work the effect of the particle impact velocity on the value of the restitution coefficient and the effect of the impact angle on the value of the normal coefficient of collision for four types of spherical particles are examined. It is found with increasing particle velocity its effect on the value of the restitution coefficient decreases and at impact angles exceeding 50o-60o, the impact angle has no effect on the value of the normal coefficient of collision. In a previous paper [1] the effect of particle diameter and the wall thickness on the value of the coefficient of restitution have been reported.
