Modelling and numerical methods for granular gases

Part of the Modeling and Simulation in Science, Engineering and Technology book series (MSSET)


We discuss certain kinetic models of dilute granular systems of spheres with dissi- pative collisions and variable coefficient of restitution. Under the assumption of weak inelastic- ity 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.
