Understanding and modelling the dynamic behaviour of particulate systems has been a
major research focus worldwide for many years. Discrete particle simulation plays an …

Vertically vibrated systems of granular materials have been used to gain insight on granular
segregation for decades. However, the majority of studies have focused on the rise of a …

The linear integral equations defining the Navier-Stokes (NS) transport coefficients for
polydisperse granular mixtures of smooth inelastic hard disks or spheres are solved by …

Using high-speed video and magnetic resonance imaging (MRI) we study the motion of a
large sphere in a vertically vibrated bed of smaller grains. As previously reported we find a …

Convection and fluidization phenomena in vibrated granular beds have attracted a strong
interest from the physics community since the last decade of the past century. As early …

We present an experimental study of the movement of individual particles in a layer of
vertically shaken granular material. High-speed imaging allows us to investigate the motion …

Executive Summary The Mars Human Precursor Science Steering Group was chartered by
MEPAG in June 2004 to analyze the priorities for precursor investigations, measurements …

We report on numerical simulations of a vibrated granular bed including the effect of the
ambient air, generating the famous Faraday heaps known from experiment. A detailed …

A combination of molecular dynamics simulations, theoretical predictions and previous
experiments are used in a two-part study to determine the role of the Knudsen layer in rapid …

Under low-frequency vertical vibration, a system of fine grains within a fluid is observed to tilt
or to form piles, an effect studied by Faraday for grains in air. Here, we investigate the …
