Abstract:
The gravity-driven flow of granular materials in a vertical channel is simulated us-
ing molecular dynamics technique. The granular particles are modelled as smooth
hard disks, so the simulations are performed in two dimensions. An event-driven
algorithm proposed by Lubachevsky [51] has used to perform simulations. The con-
trol paramters are : volume fraction of particles (?), normal restitution coefficient
(en) that characterises the loss due to particle-particle collisions and tangential
restitution coefficient (?w) that characterises the energy loss due to particle-wall
collisions. We have studied various aspects of granular Poiseuille flow (GPF) over
a range of the control paramters.
