Uniform self-diffusion in a granular gas
(American Institute of Physics, 2013)
A granular gas composed of inelastic hard spheres or disks in the homogeneous cooling state is considered. Some of the particles are labeled and their number density exhibits a time-independent linear profile along a given ...

Shearing instability of a dilute granular mixture
(American Physical Society, 2013)
The shearing instability of a dilute granular mixture composed of smooth inelastic hard spheres or disks is investigated. By using the Navier-Stokes hydrodynamic equations, it is shown that the scaled transversal velocity ...

Steady self-diffusion in classical gases
(IOP Publishing Ltd., 2013-08)
A steady self-diffusion process in a gas of hard spheres at equilibrium is analyzed. The system exhibits a constant gradient of labeled particles. Neither the concentration of these particles nor its gradient are assumed ...
