This review article aims to provide a comprehensive and understandable account of the
theoretical foundation, modeling issues, and numerical implementation of the Lagrangian …

One challenge of today's research is the realistic simulation of granular materials, like sand
or powders, consisting of millions of particles. In this article, the discrete element method …

We discuss methods to compute the flow of non-Brownian, non-cohesive, and non-spherical
rigid bodies immersed in a single homogeneous fluid. We address both the case of …

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 hydraulic transport of coarse particles in a vertical pipe is simulated in this work and the
influences of different mechanisms of the fluid-particle interactions on the liquid-solid flow …

A hydrodynamic description for an s-component mixture of inelastic, smooth hard disks (two
dimensions) or spheres (three dimensions) is derived based on the revised Enskog theory …

In contrast to normal fluids, a granular fluid under shear supports a steady state with uniform
temperature and density since the collisional cooling can compensate locally for viscous …

It is well-known that in a dense, gravity-driven flow, large particles typically rise to the top
relative to smaller equal-density particles. In dense flows, this has historically been attributed …

We study the rheology of granular mixtures in a steady, fully developed, gravity-driven flow
on an inclined plane, by means of discrete element method (DEM) simulations. Results are …

The effects of particle size and/or density on particle interaction and overall behavior of
granular flow were studied using the kinetic theory approach. The kinetic theory for granular …
