Cluster dynamics in dense granular gases of rod-like particles

Granular gases are interesting multiparticle systems which, irrespective of the apparent simplicity particle interactions, exhibit a rich scenario so far only little understood features. We have numerically investigated dense granular gas composed frictional spherocylinders which excited mechanically by lateral vibrating container walls. This study was stimulated experiments in microgravity on parabolic flights. The formation spatial inhomogeneities (clusters) observed region near corners container, about halfway from excitation plates. particles clusters show tendency to align parallel walls, seemingly increasing stabilizing effect friction. simulation results provide hints that phase difference vibrations two walls might affect cluster dynamics.
