This paper provides a review on the flow of free-flowing coarse particles inside silos. Basic
principles and elementary mechanisms involved in gravity flow of granular materials are …

Pebble-bed nuclear reactor technology, which is currently being revived around the world,
raises fundamental questions about dense granular flow in silos. A typical reactor core is …

Granular flow in a rotating tumbler is of theoretical and industrial significance. However, in
spite of its relative simplicity, little is known about the dynamics of the top flowing layer. Here …

We measure the flow of granular materials inside a quasi-two-dimensional silo as it drains
and compare the data with some existing models. The particles inside the silo are imaged …

We study the transport properties of particles draining from a silo using imaging and direct
particle tracking. The particle displacements show a universal transition from superdiffusion …

The paper presents results of deformation measurements in dry cohesionless sand during
free flow in small rectangular model silos using a non-invasive, indirect method called …

By using the discrete element method (DEM) a comparison and observations on material
flow patterns in plane-wedged, space-wedged, and flat-bottomed hopper were accounted …

The measurements of the width of a localized zone on the surface of notched concrete
beams under quasi-static three-point bending were performed using the 2D Digital Image …

In this paper, both time-averaged and fluctuating behaviors of granular solids in a two-
dimensional spouted bed (2DSB) were investigated by particle image velocimetry (PIV). A …

Continuum mechanics relies on the fundamental notion of a mesoscopic volume “element”
in which properties averaged over discrete particles obey deterministic relationships. Recent …
