Segregation in dry granular systems
Abstract
Segregation in rotating drums is studied experimentally in two and three dimensions with unexpected results. In the first case, we find that the spatial grain distribution oscillates between uniform and segregated states when the drum rotates below the fluidization regime. In three dimensions we find the startling result that the system axially segregates at (very) long times, and that the previously reported patterns are long lived transients.
