Cluster Growth in two- and three-dimensional Granular Gases

TL;DR

This paper investigates how clusters form and evolve over time in granular gases in two and three dimensions, revealing parallels to percolation theory and analyzing energy decay and clustering dynamics.

Contribution

It provides new insights into cluster growth and energy decay in granular gases, highlighting parallels with percolation phenomena in three dimensions.

Findings

Cluster formation occurs in both 2D and 3D granular gases.

Energy decay follows specific non-equilibrium patterns.

Percolation-like behavior observed in 3D systems.

Abstract

Dissipation in granular media leads to interesting phenomena as there are cluster formation and crystallization in non-equilibrium dynamical states. The freely cooling system is examined concerning the energy decay and the cluster evolution in time, both in two and three dimensions. Interesting parallels to percolation theory are obtained in three dimensions.
