Shear-driven size segregation of granular materials: modeling and experiment.

The Gray-Thornton model of segregation is applied to a granular flow with an exponential shear profile, and the model successfully captures the presence of a fast mixing process and relatively slower resegregation process, but the model predicts a finite resegregation time, while in the experiment resegregation occurs only exponentially in time.

Modelling density segregation in flowing bidisperse granular materials

Preventing segregation in flowing granular mixtures is an ongoing challenge for industrial processes that involve the handling of bulk solids. A recent continuum-based modelling approach accurately

Density difference-driven segregation in a dense granular flow

Abstract We consider the segregation of spheres of equal size and different density flowing over an inclined plane, theoretically and computationally by means of distinct element method (DEM)

Radial segregation of granular mixtures in rotating cylinders

Simultaneous mixing and segregation of granular materials is of considerable practical importance; the interplay among both processes is, however, poorly understood from a fundamental viewpoint. The

Experimental investigation and kinetic-theory-based model of a rapid granular shear flow

An experimental investigation of an idealized rapidly sheared granular flow was performed to test the predictions of a model based on the kinetic theory of dry granular media. Glass ballotini beads

A mixture theory for size and density segregation in shallow granular free-surface flows

Abstract In the past ten years much work has been undertaken on developing mixture theory continuum models to describe kinetic sieving-driven size segregation. We propose an extension to these models

Particle-size and -density segregation in granular free-surface flows

When a mixture of particles, which differ in both their size and their density, avalanches downslope, the grains can either segregate into layers or remain mixed, dependent on the balance between

Rheology of binary granular mixtures in the dense flow regime

We study the rheology of granular mixtures in a steady, fully developed, gravity-driven flow on an inclined plane, by means of discrete element method (DEM) simulations. Results are presented for a

Shear localization and wall friction in confined dense granular flows

In this work, we discuss experiments and discrete element simulations of wall-bounded shear flows of slightly polydisperse spheres under gravity. Experiments were performed in an annular shear cell

Investigation of shear rate gradients and associated gradients in velocity fluctuations in mixtures of particles differing in material density finds that heavier (denser) particles segregate to regions of lower shear rates and lower granular temperatures, in contrast with segregation of different-sized particles at high f, where the heavier (larger) particles segregationate to the region of higherShear rates.
