Gas-solid fluidization technology has been commercialized in many industrial applications
since its implementation in the fluid catalytic cracking process in the early 1940s, however …

Dense granular materials display a complicated set of flow properties, which differentiate
them from ordinary fluids. Despite their ubiquity, no model has been developed that captures …

A recent granular rheology based on an implicit “granular fluidity” field has been shown to
quantitatively predict many nonlocal phenomena. However, the physical nature of the field …

Dry, frictional, steady-state granular flows down an inclined, rough surface are studied with
discrete particle simulations. From this exemplary flow situation, macroscopic fields …

The so-called coarse-grained discrete element method (DEM) is used here for efficient
simulations of large-scale particle systems as its effectiveness has been successfully verified …

A constitutive model is developed for the complex rheology of rate-independent granular
materials. The closures for the pressure and the macroscopic friction coefficient are linked to …

We propose a technique to simulate granular materials that exploits the dual strengths of
discrete and continuum treatments. Discrete element simulations provide unmatched levels …

Abstract Using a continuum Navier-Stokes solver with the μ (I) flow law implemented to
model the viscous behavior, and the discrete Contact Dynamics algorithm, the discharge of …

This work proposes a model for granular deformation that predicts the stress and velocity
profiles in well-developed dense granular flows. Recent models for granular elasticity [Jiang …

Conventional plasticity models follow rich mathematical formulations. However, they
typically lack a physical basis, so their predictive quality is strongly correlated with the …
