Granular Gas DynamicsThorsten Pöschel, Nikolai V. Brilliantov The contributions in this book address both the kinetic approach one using the Boltzmann equation for dissipative gases as well as the less established hydrodynamic description. The last part of the book is devoted to driven granular gases and their analogy with molecular fluids. |
