Sand, rice, sugar, snow, cement... Although ubiquitous in our daily lives, granular media still
challenge engineers and fascinate researchers. This book provides the state-of-the-art of the …

We present a new instability observed in rapid granular flows down rough inclined planes.
For high inclinations and flow rates, the free surface of the flow experiences a regular …

The first normal stress difference (N 1) and the microstructure in a dense sheared granular
fluid of smooth inelastic hard-disks are probed using event-driven simulations. While the …

Strongly vertically shaken granular matter can display a density inversion: A high-density
cluster of beads is elevated by a dilute gaslike layer of fast beads underneath (“granular …

The physics of granular flows is a fascinating subject because a range of complex collective
behaviour arise from seemingly simple microscopic interactions between the individual …

We numerically investigate, through discrete element simulations, the steady flow of
identical, frictionless spheres sheared between two parallel, bumpy planes in the absence of …

In a recent article (Forterre & Pouliquen 2001), we have reported a new instability observed
in rapid granular flows down inclined planes that leads to the spontaneous formation of …

We have studied plane shear flow of nearly homogeneous assemblies of uniformly sized,
spherical particles in periodic domains. Our focus has been on the effect of interparticle …

The inelastic Boltzmann equation for a granular gas is applied to spatially inhomogeneous
states close to uniform shear flow. A normal solution is obtained via a Chapman-Enskog-like …

This article is a review of recent theoretical work on shear flow instabilities of particulate
suspensions and dry granular medium. Attention is devoted largely to steady homogeneous …
