Various Phenomena of Vibrated Non-Uniform Granular Particles

Abstract

Identical granular particles in multiple compartments on a vertically shaking table may show an aggregation phenomenon termed granular Maxwell's demon for a suitable choice of parameters. Vertically vibrated binary granular particles may yield granular Maxwell's demon or the granular clock. Horizontally vibrated binary granular particles may form stripe patterns perpendicular or parallel to the vibratory direction for a suitable choice of parameters. Influences on the above-mentioned phenomena were analyzed, when the diameter or the mass of granular particles was distributed.
