Abstract
We carry out computational study of pattern formation during cooling in assemblies of inelastically colliding granular particles, under force free condition. Typically, in such systems, following a homogeneous cooling phase, a crossover occurs to a phase that is defined by the inhomogeneity in the density field. This inhomogeneity is known to persist for the remaining part of the evolution process, if the coefficient of restitution (e) is chosen to be a constant. However, in real situations, e depends upon the relative velocity of the colliding partners. In this work, we choose a model that mimics this scenario. In addition to presenting results on the pattern dynamics, an important objective of the work is to initiate a study for obtaining a picture on the effectiveness of model parameters.
