This review article provides an overview of dry granular flows and particle fluid mixtures,
including experimental and numerical modeling at the laboratory scale, large scale …

Many subgrid drag modifications have been put forth to account for the effect of small
unresolved scales on the resolved mesoscales in dense gas‐particle flows. These subgrid …

Recent progresses in understanding the behavior of dense granular flows are presented.
After presenting a bulk rheology of granular materials, I focus on the new developments to …

We report numerical simulations on granular shear flows confined between two flat but
frictional sidewalls. Novel regimes differing by their strain localization features are observed …

This paper derives new boundary conditions for the solids stresses and the flux of fluctuation
energy for collisional granular flows of spheres at flat frictional moving walls. In contrast to …

Hydrodynamic approaches that treat granular materials as a continuum via the
homogenization of discrete flow properties have become viable options for efficient …

In our prior study (Schneiderbauer, AIChE J, 2017; 63 (8): 3544–3562), we presented a
spatially averaged two‐fluid model, where closure models for the unresolved terms were …

The present paper is concerned with the two-dimensional collapse of piles of granular
materials, a problem analogous to the classical dam break problem in hydraulics. This study …

We report on a numerical study of the shear flow of a simple two-dimensional model of a
granular material under controlled normal stress between two parallel smooth frictional walls …

In this Letter, the two-dimensional dense flow of polygonal particles on an incline with a flat
frictional inferior boundary is analyzed by means of contact dynamics discrete element …
