Self-diffusion in freely evolving granular gases
(American Institute of Physics, 1994)
A self-diffusionequation for a freely evolving gas of inelastic hard disks or spheres is derived starting from the Boltzmann–Lorentz equation, by means of a Chapman–Enskog expansion in the density gradient of the tagged ...

Brownian motion in a granular gas
(American Physical Society, 1999)
The dynamics of a heavy particle in a gas of much lighter particles is studied via the Boltzmann-Lorentz equation with inelastic collisions among all particles. A formal expansion in the ratio of gas to tagged particle ...

Transversal inhomogeneities in dilute vibrofluidized granular fluids
(American Physical Society, 2002)
The spontaneous symmetry breaking taking place in the direction perpendicular to the energy flux in a dilute vibrofluidized granular system is investigated, using both a hydrodynamic description and simulation methods. The ...
