Granular segregation as a critical phenomenon

Pedro M. Reis, Tom Mullin

Research output: Contribution to journal › Article › peer-review

Abstract

The results of an experimental study of patterned segregation in a horizontally shaken shallow layer of a binary mixture of dry particles are presented. The effect of the variation of the combined filling fraction, C, of the mixture on the observed pattern formation is studied. It is found that there is a critical event associated with the onset of segregation, at Cc = 0.647 ± 0.049, which has the characteristics of a continuous phase transition, including critical slowing down.
