Freely Cooling systems

Dissipation, together with excluded volume, are the two most important characteristics of granular media. Freely cooling granular gases present coexistence of extremely dilute regions with very high density solid clusters. The basic idea of clustering is that in an initially homogeneous state, fluctuations in density, velocity, and temperature cause a position dependent energy loss. In our group we study the dynamics of such states as a function of the interaction law between particles, as also for polydisperse cases.
