Pseudo 2-Dimensional Trajectory of a Particle in Vibrating Granular Bed

Panupat Chaiworn, Fei Fang Chung, and Sy-Sang Liaw
Abstract—We experimentally study how the convection patterns of the pseudo two-dimensional granular systems under vibration are affected by the friction between the granules and the side walls of the container. We show that the number of convection cells and the direction of granule velocity are strongly dependent on the magnitudes of the friction. These are adjusted in our experiments by changing the surface property of the container walls, wall motion, and granular height. The larger the friction between the granules and the side wall, the larger the convection cell it generates, and consequently the fewer number of cells the system has. The friction-dependent property of the convection cells is unique to granules not shared by fluid.
