Diffusion in multicomponent granular mixtures

Soft Condensed Matter 2024-03-21 v3 Statistical Mechanics

Abstract

We investigate diffusion in a polydisperse granular media. We derive mean-squared displacement of granular particles in a polydisperse granular gas in a homogeneous cooling state, containing arbitrary amount of species of different sizes and masses. We investigate both models of constant and time-dependent restitution coefficients and obtain a universal law for the size-dependence of MSD for steep size distributions.
