A constitutive law for dense granular flows
A continuum description of granular flows would be of considerable help in predicting natural geophysical hazards or in designing industrial processes. However, the constitutive equations for dryExpand

SCALING LAWS IN GRANULAR FLOWS DOWN ROUGH INCLINED PLANES
In this paper, new scaling properties for granular flows down rough inclined planes are presented. In the dense steady uniform flow regime, we have systematically measured the mean velocity of theExpand

Unifying suspension and granular rheology.
Using an original pressure-imposed shear cell, we study the rheology of dense suspensions. We show that they exhibit a viscoplastic behavior similarly to granular media successfully described by aExpand

Flows of Dense Granular Media
We review flows of dense cohesionless granular materials, with a special focus on the question of constitutive equations. We first discuss the existence of a dense flow regime characterized byExpand

Crucial role of side walls for granular surface flows: consequences for the rheology
In this paper we study the steady uniform flows that develop when granular material is released from a hopper on top of a static pile in a channel. We more specifically focus on the role of sideExpand

Friction law for dense granular flows: application to the motion of a mass down a rough inclined plane
The problem of the spreading of a granular mass released at the top of a rough inclined plane was investigated. The evolution of the avalanche was measured experimentally from the initiation up toExpand

Submarine granular flows down inclined planes
Submarine flows of granular material down a rough inclined plane are experimentally investigated. We focus on the dense flow regime when the whole sediment layer is flowing down the slope and when noExpand

Rheology of dense granular suspensions
Suspensions are composed of mixtures of particles and fluid and are omnipresent in natural phenomena and in industrial processes. The present paper addresses the rheology of concentrated suspensionsExpand

ON THE SHAPE OF GRANULAR FRONTS DOWN ROUGH INCLINED PLANES
The shape of fronts obtained when releasing a cohesionless granular material at the top of a rough inclined plane is experimentally investigated. The measurements are compared with theoreticalExpand
