Sliding contact fraction in gravity-driven dense cohesionless granular flows

Patrick Richard, Riccardo Artoni, Clovis Lambert +2

Using large-scale, three-dimensional discrete element simulations, we investigate the kinematic properties of granular chute flows of cohesionless grains, together with the evoluti…

Self-diffusion in inhomogeneous granular shearing flows

Riccardo Artoni, Michele Larcher, James Jenkins +1

In this letter, we discuss how flow inhomogeneity affects the self-diffusion behavior in granular flows. Whereas self-diffusion scalings have been well characterized in the past fo…

Granular surface flows confined between flat, frictional walls. Part 1. Kinematics

Patrick Richard, Alexandre Valance, Renaud Delannay +1

We report and analyse the results of extensive discrete element method simulations of three-dimensional gravity driven flows of cohesionless granular media over an erodible bed, th…

Experimental investigation and numerical modelling of density-driven segregation in an annular shear cell

Monica Tirapelle, Andrea Santomaso, Patrick Richard +1

Granular materials segregate spontaneously due to differences in particle size, shape, density and flow behaviour. In this paper we experimentally investigate density-difference-dr…

Self-Diffusion Scalings in Dense Granular Flows

Riccardo Artoni, Michele Larcher, James Jenkins +1

We report on measurements of self-diffusion coefficients in discrete numerical simulations of steady, homogeneous, collisional shearing flows of nearly identical, frictional, inela…

Influence of lateral confinement on granular flows: comparison between shear-driven and gravity-driven flows

Patrick Richard, Riccardo Artoni, Alexandre Valance +1

The properties of confined granular flows are studied through discrete numerical simulations. Two types of flows with different boundaries are compared: (i) gravity-driven flows to…
