Granular Gas Cooling and Relaxation to the Steady State in Regard to the Overpopulated Tail of the Velocity Distribution

Thorsten Poeschel, Nikolai V. Brilliantov, Arno Formella

We present a universal description of the velocity distribution function of granular gases, $f(v)$, valid for both, small and intermediate velocities where $v$ is close to the ther…
