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…
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…
Effect of contact location on the crushing strength of aggregates
Riccardo Artoni, Aurélien Neveu, Yannick Descantes +1
This work deals with the effect of the contact location distribution on the crushing of granular materials. At first, a simple drop weight experiment was designed in order to study…
Heat convection and radiation in flighted rotary kilns: A minimal model
Laurédan Le Guen, Maxime Piton, Quentin Hénaut +2
We propose a minimal model aiming to describe heat transfer between particles (i.e. grains) and gases in a model of flighted rotary kilns. It considers a channel in which a convect…
