TLDR
In this article, the segregation coefficient was measured and found to increase with vibrational acceleration until reaching a maximum and then to decrease with acceleration, and the greatest segregation effect occurred when the bed transformed from a dense state to a loose state.About:

Convection cells and segregation in a vibrated granular bed
TL;DR: In this paper, the wall roughness and vibration velocity amplitude are also changed to investigate their influences on the convection cell strength and segregation process in a container with two symmetric convection cells under external vertical vibration conditions.

Density segregation in a vertically vibrated granular bed
TL;DR: In this paper, different densities of granular materials with different filling layers and packing ratios were used to investigate the segregation mechanisms in a vibrated granular bed in order to track the motion of granul materials.

Kinetic theories for granular flow: inelastic particles in Couette flow and slightly inelastic particles in a general flowfield
TL;DR: In this paper, the authors studied the flow of an idealized granular material consisting of uniform smooth, but nelastic, spherical particles using statistical methods analogous to those used in the kinetic theory of gases.
Journal ArticleDOI
A theory for the rapid flow of identical, smooth, nearly elastic, spherical particles
TL;DR: In this article, the authors focus on an idealized granular material comprised of identical, smooth, imperfectly elastic, spherical particles which is flowing at such a density and is being deformed at a rate that particles interact only through binary collisions with their neighbours.
Journal ArticleDOI
Rapid granular flows
TL;DR: In this article, the authors present a review of the fluid-like behavior of granular solids and, in particular, those flows for which the material is rapidly sheared, and discuss various modeling techniques used to describe the motion of the bulk material.
Journal ArticleDOI
Physics of the Granular State
TL;DR: The generation of analogies between the physics found in a simple sandpile and that found in complicated microscopic systems, such as flux motion in superconductors or spin glasses, has prompted a number of new theories and to a new era of experimentation on granular systems.
