Generalized time evolution of the homogeneous cooling state of a granular gas with positive and negative coefficient of normal restitution

open access: yes, 2018
The homogeneous cooling state (HCS) of a granular gas described by the inelastic Boltzmann equation is reconsidered. As usual, particles are taken as inelastic hard disks or spheres, but now the coefficient of normal restitution $\alpha$ is allowed to ...

Hydrodynamics of inelastic Maxwell models

open access: yes, 2011
An overview of recent results pertaining to the hydrodynamic description (both Newtonian and non-Newtonian) of granular gases described by the Boltzmann equation for inelastic Maxwell models is presented.

Relative Entropy of a Freely Cooling Granular Gas

open access: yes, 2012
The time evolution and stationary values of the entropy per particle of a homogeneous freely cooling granular gas, relative to the maximum entropy consistent with the instantaneous translational and rotational temperatures, is analyzed by means of a ...

Homogeneous steady states in a granular fluid driven by a stochastic bath with friction

open access: yes, 2013
The homogeneous state of a granular flow of smooth inelastic hard spheres or disks described by the Enskog-Boltzmann kinetic equation is analyzed. The granular gas is fluidized by the presence of a random force and a drag force.
