Critical scaling and soft granular rheology of frictionless non-Brownian suspensions across jamming
Rohan Vernekar, Romain Mari, Bruno Chareyre +1
We carry out 3D computer simulations to study suspension rheology across the jamming transition for deformable non-Brownian frictionless particles. The simulations are carried out…
Normal viscosity and Viscous resuspension of non-Brownian suspensions
William Chèvremont, Bruno Chareyre, Hugues Bodiguel
Normal stresses in sheared suspensions of non-Brownian particles are obtained from numerical simulations in the viscous regime. The stresses are determined in homogeneous shear of…
Localized fluidization in granular materials: Theoretical and numerical study
E. P. Montellà, M. Toraldo, B. Chareyre +1
We present analytical and numerical results on localized fluidization within a granular layer subjected to a local injection of fluid. As the injection rate increases the three dif…
Pore-scale simulations of drainage in granular materials: finite size effects and the representative elementary volume
Chao Yuan, Bruno Chareyre, Félix Darve
A pore-scale model is introduced for two-phase flow in dense packings of polydisperse spheres. The model is developed as a component of a more general hydromechanical coupling fram…
Microscopic origins of shear stress in dense fluid-grain mixtures
Donia Marzougui, Bruno Chareyre, Julien Chauchat
A numerical model is used to simulate rheometer experiments at constant normal stress on dense suspensions of spheres. The complete model includes sphere-sphere contacts using a so…
Pore-scale modeling of fluid-particles interaction and emerging poromechanical effects
Emanuele Catalano, Bruno Chareyre, Eric Barthélémy
A micro-hydromechanical model for granular materials is presented. It combines the discrete element method (DEM) for the modeling of the solid phase and a pore-scale finite volume…
