Coarse-grained local and objective continuum description of three-dimensional granular flows down an inclined surface

Dry, frictional, steady-state granular flows down an inclined, rough surface are studied with discrete particle simulations. From this exemplary flow situation, macroscopic fields, consistent with the conservation laws of continuum theory, are obtained from microscopic data by time-averaging and spatial smoothing (coarse-graining). Two distinct coarse-graining length scale ranges are identified...

Unsteady granular flows down an inclined plane.

The continuum description of granular flows is still a challenge despite their importance in many geophysical and industrial applications. We extend previous works, which have explored steady flow properties, by focusing on unsteady flows accelerating or decelerating down an inclined plane in the simple shear configuration. We solve the flow kinematics analytically, including predictions of evo...

Three-dimensional Modelling of Industrial Granular Flows

The Discrete Element Method (DEM) is attracting increasing interest for the simulation of industrial granular flows. While the majority of previous DEM modelling has considered two-dimensional flows, we present here a series of three-dimensional simulations for a number of important industrial applications. The charge motion in a 5 m diameter ball mill and in a Hicom nutating mill, discharge fr...

Granular flow down an inclined plane: Bagnold scaling and rheology.

We have performed a systematic, large-scale simulation study of granular media in two and three dimensions, investigating the rheology of cohesionless granular particles in inclined plane geometries, i.e., chute flows. We find that over a wide range of parameter space of interaction coefficients and inclination angles, a steady-state flow regime exists in which the energy input from gravity bal...

An experimental study on hydraulic behavior of free-surface radial flow in coarse-grained porous media

The equations of fluids in porous media are very useful in designing the rockfill and diversion dams, gabions, breakwaters and ground water reserves. Researches have been showed that the Forchheimer equation is not sufficient for the analysis of hydraulic behavior of free-surface radial flows; because, in these flows, in addition to the hydraulic gradient and velocity, the variable of radius is...
