Effect of Shape and Friction on the Packing and Flow of Granular Materials
K. Michael Salerno, Dan S. Bolintineanu, Gary S. Grest +4
The packing and flow of aspherical frictional particles are studied using discrete element simulations. Particles are superballs with shape that varie…
Stratification of drying particle suspensions: Comparison of implicit and explicit solvent simulations
Yanfei Tang, Gary S. Grest, Shengfeng Cheng
Large scale molecular dynamics simulations are used to study drying suspensions of a binary mixture of large and small particles in explicit and implicit solvents. The solvent is f…
Control of Stratification in Drying Particle Suspensions via Temperature Gradients
Yanfei Tang, Gary S. Grest, Shengfeng Cheng
A potential strategy for controlling stratification in a drying suspension of bidisperse particles is studied using molecular dynamics simulations. When the suspension is maintaine…
Flow-Arrest Transitions in Frictional Granular Matter
Ishan Srivastava, Leonardo E. Silbert, Gary S. Grest +1
The transition between shear-flowing and shear-arrested states of frictional granular matter is studied using constant-stress discrete element simulations. By subjecting a dilute s…
Stratification in Drying Films Containing Bidisperse Mixtures of Nanoparticles
Yanfei Tang, Gary S. Grest, Shengfeng Cheng
Large scale molecular dynamics simulations for bidisperse nanoparticle suspensions with an explicit solvent are used to investigate the effects of evaporation rates and volume frac…
