Particles, trajectories and diffusion: random walks in cooling granular gases
Santos Bravo Yuste, Rubén Gómez González, Vicente Garzó
We study the mean-square displacement (MSD) of a tracer particle diffusing in a granular gas of inelastic hard spheres under homogeneous cooling state (HCS). Tracer and granular ga…
Diffusion of intruders in a granular gas thermostatted by a bath of elastic hard spheres
Rubén Gómez González, Vicente Garzó
The Boltzmann kinetic equation is considered to compute the transport coefficients associated with the mass flux of intruders in a granular gas. Intruders and granular gas are imme…
Diffusion of impurities in a moderately dense confined granular gas
Rubén Gómez González, Vicente Garzó, Ricardo Brito +1
Mass transport of impurities immersed in a confined quasi-two-dimensional moderately dense granular gas of inelastic hard spheres is studied. The effect of the confinement on granu…
Gaseous Diffusion as a Correlated Random Walk
Santos Bravo Yuste, Rubén Gómez González, Vicente Garzó
The mean square displacement per collision of a molecule immersed in a gas at equilibrium is given by its mean square displacement between two consecutive collisions (mean square f…
Rheology of granular particles immersed in a molecular gas under uniform shear flow
Rubén Gómez González, Moisés GarcÃa Chamorro, Vicente Garzó
Non-Newtonian transport properties of a dilute gas of inelastic hard spheres immersed in a molecular gas are determined. We assume that the granular gas is sufficiently rarefied an…
