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…
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…
Predictions of microstructure and stress in planar extensional flows of a dense viscous suspension
James T. Jenkins, Ryohei Seto, Luigi La Ragione
We consider extensional flows of a dense layer of spheres in a viscous fluid and employ force and torque balances to determine the trajectory of particle pairs that contribute to t…
Comments on avalanche flow models based on the concept of random kinetic energy
Dieter Issler, James T. Jenkins, Jim N. McElwaine
In a series of papers, Bartelt and co-workers developed novel snow-avalanche models in which \emph{random kinetic energy} (a.k.a.\ granular temperature) is a key concept. The…
How granular materials deform in quasistatic conditions
Jean-Noël Roux, Gaël Combe
Based on numerical simulations of quasistatic deformation of model granular materials, two rheological regimes are distinguished, according to whether macroscopic strains merely re…
Irreversible Incremental Behavior in a Granular Material
Luigi La Ragione, Vanessa Magnanimo, James T. Jenkins +1
We test the elasticity of granular aggregates using increments of shear and volume strain in a numerical simulation. We find that the increment in volume strain is almost reversibl…
