Several theoretical predictions of the mass flow rate of granular media discharged from a silo are based on the spontaneous development of a free-fall arch region, the existence of …

Outflow of granular material through a small orifice is a fundamental process in many industrial fields, for example in silo discharge, and in everyday's life. Most experimental …

Granular material flowing through bottlenecks, like the openings of silos, tend to clog and thus inhibit further flow. We study this phenomenon in a three-dimensional hopper for …

Using experiments and simulations, we study the flow of soft particles through quasi-two- dimensional hoppers. The first experiment uses oil-in-water emulsion droplets in a thin …
Soft, low-friction particles in silos show peculiar features during their discharge. The outflow velocity and the clogging probability both depend upon the momentary silo fill height, in …

Abstract Two-dimensional (2D) hopper flow of disks has been extensively studied. Here, we investigate hopper flow of ellipses with aspect ratio $\alpha= 2$, and we contrast that …
Precise evaluation of mass discharge rate (MDR) in hoppers is an important topic in many industries. Facilitated by an Eulerian-formulation finite element method (FEM), this paper …

Mechanical behaviour of powders and grains often displays features of solid-like and liquid- like characteristics of matter. In spite of processing granular materials quite extensively in the …
Outflow of granular materials from silos is a remarkably complex physical phenomenon that has been extensively studied with simple objects like monodisperse hard disks in two …
