Wall-Enhanced Convection in Vibrofluidized Granular Systems
An event-driven molecular dynamics simulation of inelastic hard spheres
contained in a cylinder and subject to strong vibration reproduces accurately
experimental results[1] for a system of vibrofluidized glass beads. In
particular, we are able to obtain the velocity field and the density and
temperature profiles observed experimentally. In addition, we show that the
appearance of convection rolls is strongly influenced by the value of the
sidewall-particle restitution coefficient. Suggestions for observing more
complex convection patterns are proposed.Comment: 4 pages, 6 figure
