Analysis of Granular Flow in a Pebble-Bed Nuclear Reactor
Chris H. Rycroft, Gary S. Grest, James W. Landry +1
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…
Dynamics of Random Packings in Granular Flow
Chris H. Rycroft, Martin Z. Bazant, Gary S. Grest +1
We present a multiscale simulation algorithm for amorphous materials, which we illustrate and validate in a canonical case of dense granular flow. Our algorithm is based on the rec…
Plug flow and the breakdown of Bagnold scaling in cohesive granular flows
Robert Brewster, Gary S. Grest, James W. Landry +1
Cohesive granular media flowing down an inclined plane are studied by discrete element simulations. Previous work on cohesionless granular media demonstrated that within the steady…
Jamming in granular hopper flow
James W. Landry, Gary S. Grest
Large-scale three dimensional molecular dynamics simulations of hopper flow are presented. The flow rate of the system is controlled by the width of the aperture at the bottom. As…
Granular packings with moving side walls
J. W. Landry, G. S. Grest
The effects of movement of the side walls of a confined granular packing are studied by discrete element, molecular dynamics simulations. The dynamical evolution of the stress is s…
Discrete element simulations of stress distributions in silos: crossover from two to three dimensions
James W. Landry, Gary S. Grest, Stephen J. Plimpton
The transition from two-dimensional (2D) to three-dimensional (3D) granular packings is studied using large-scale discrete element computer simulations. We focus on vertical stress…
