A computational particle flow simulation of a feeder which transports bulk material through a
horizontal cylinder by a turning screw is presented. The objective is hereby the simulation …

Four representative studies were selected to investigate industrial ventilation guidelines for
controlling smoke, dust, droplets and waste heat. In the first case, exhaust hoods were …

Flexible obstacles are used to reduce the impact load exerted by granular flows. However,
grain-scale interactions between granular assemblies and flexible obstacles remain poorly …

The drag force law acting on a moving circular disk in a two-dimensional granular medium is
analyzed based on the discrete element method (DEM). It is remarkable that the drag force …

Dynamic behaviors of non-circular dense granular jets impacting a sufficiently large target
are studied by experiment and DEM simulation. Effects of the granular jet velocity, particle …

When a dense granular jet hits a target, it forms a large dead zone and ejects a highly
collimated conical sheet with a well-defined opening angle. Using experiments, simulations …

We investigate the impact of a granular jet on a finite target by means of particle simulations.
The resulting hydrodynamic fields are compared with theoretical predictions for the …

Using high-speed photography, we investigate two distinct regimes of the impact dynamics
of granular jets with noncircular cross sections. In the steady-state regime, we observe the …

This study numerically and analytically investigates the dynamics of a rotor under viscous or
dry friction as a nonequilibrium probe of a granular gas. In order to demonstrate the role of …

Dynamic behaviors of dense granular jets impacting a flat target are experimentally studied
and numerically simulated using the Discrete Element Method. Effects of the granular jet …
