Relaxation of perturbed axial segregation bands

Issue Date

Abstract

The mixture of grains inside a rotating horizontal cylinder segregate into alternating bands of big and small grains along the rotation axis at appropriate conditions. However, the response of these bands to perturbations is largely unexplored. Here, we report that, when deformed by a weak localized perturbation from one end of the cylinder, the axial bands relax to their original positions after several rotations of the cylinder. Considering that relaxation in other physical systems is related to their structure and dynamics, this robust phenomenon could have interesting implications on our understanding of granular materials.
