Diffusion as mixing mechanism in granular materials
C. Henrique, G. Batrouni, D. Bideau
We present several numerical results on granular mixtures. In particular, we examine the efficiency of diffusion as a mixing mechanism in these systems. The collisions are inelasti…
Effect of boundary conditions on diffusion in two-dimensional granular gases
C. Henrique, G. Batrouni, D. Bideau
We analyze the influence of boundary conditions on numerical simulations of the diffusive properties of a two dimensional granular gas. We show in particular that periodic boundary…
Vesicle propulsion in haptotaxis : a local model
Isabelle Cantat, Chaouqi Misbah, Yukio Saito
We study theoretically vesicle locomotion due to haptotaxis. Haptotaxis is referred to motion induced by an adhesion gradient on a substrate. The problem is solved within a local a…
Dynamics of aeolian sand ripples
Z. Csahok, C. Misbah, F. Rioual +1
We analyze theoretically the dynamics of aeolian sand ripples. In order to put the study in the context we first review existing models. We argue on the local character of sand rip…
