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…
Collective alignment controls rotation frustration in granular flows of elongated particles
Antonio Pol, Riccardo Artoni, Patrick Richard
Dense granular flows made of elongated particles exhibit a strong inhibition of particle rotation compared to spherical grains, but the mechanisms responsible for this effect remai…
Complex segregation patterns in confined nonuniform granular shearing flows
Santiago Caro, Riccardo Artoni, Patrick Richard +2
When polydisperse granular systems are sheared, the transverse dynamics is characterized by the interplay of size segregation and diffusion. Segregation in nonuniform and confined…
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…
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…
