Abstract

We discuss certain kinetic models of dilute granular systems of spheres with dissipative collisions and variable coefficient of restitution. Under the assumption of weak inelasticity the cooling process of the system is studied and some hydrodynamical models are derived. Accurate numerical methods based on a spectral representation in velocity are also presented and the development of fast algorithms is considered.
