Granular gas of inelastic and rough Maxwell particles
Gilberto M. Kremer, Andrés Santos
The most widely used model for granular gases is perhaps the inelastic hard-sphere model (IHSM), where the grains are assumed to be perfectly smooth spheres colliding with a consta…
Impact of roughness on the instability of a free-cooling granular gas
Vicente Garzó, Andrés Santos, Gilberto M. Kremer
A linear stability analysis of the hydrodynamic equations with respect to the homogeneous cooling state is carried out to identify the conditions for stability of a granular gas of…
Properties of the Homogeneous Cooling State of a Gas of Inelastic Rough Particles
Francisco Vega Reyes, Andrés Santos, Gilberto M. Kremer
In this work we address the question of whether a low-density system composed of identical rough particles may reach hydrodynamic states (also called \textit{normal} states), even…
Role of roughness on the hydrodynamic homogeneous base state of inelastic spheres
F. Vega Reyes, A. Santos, G. M. Kremer
A gas of inelastic rough spheres admits a spatially homogeneous base state which turns into a hydrodynamic state after a finite relaxation time. We show that this relaxation time i…
Relative Entropy of a Freely Cooling Granular Gas
Andrés Santos, Gilberto M. Kremer
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…
Sonine approximation for collisional moments of granular gases of inelastic rough spheres
Andrés Santos, Gilberto M. Kremer, Marcelo dos Santos
We consider a dilute granular gas of hard spheres colliding inelastically with coefficients of normal and tangential restitution and , respectively. The basic quantities cha…
Energy production rates in fluid mixtures of inelastic rough hard spheres
Andrés Santos, Gilberto M. Kremer, Vicente Garzó
The aim of this work is to explore the combined effect of polydispersity and roughness on the partial energy production rates and on the total cooling rate of a granular fluid mixt…
