Abstract

A numerical model which accounts for collisional and surface frictional dissipation and their influence on particle dynamics for a quasi-two dimensional cooling initially on dilute granular material was presented. It was assumed that collision dynamics was determined solely by the incoming velocity and angular velocities of the colliding particles. The kinetic friction played a dominant role in determing the dynamics of quasi-two-dimensional multiparticle system. Analysis shows that on average, particle-wall collisions lead to more dissipation than particle-particle collision for a single particle for fixed restitutional parameters.
