Scaling Laws for the Segregation Forces in Sheared Granular Flows
Abstract eng: In order to better understand the mechanism governing segregation in granular flows, the force experienced by a large particle embedded in a granular flow made of small particles is studied using discrete numerical simulations. Accurate force measurements have been obtained in a large range of flow parameters by trapping the large particle in an harmonic potential well to mimic an optical probe. An empirical expression of the segregation force is proposed as a function of the stress distribution.
