Velocity Correlations in Dense Gravity Driven Granular Chute Flow
Oleh Baran, Deniz Ertas, Gary S. Grest +2
We report numerical results for velocity correlations in dense, gravity-driven granular flow down an inclined plane. For the grains on the surface layer, our results are consistent…
Coherent Structures in Dense Granular Flows
Thomas C. Halsey, Deniz Ertas
We present a theoretical derivation of a rheology for dense granular flow, based on the process of inelastic collapse of neighboring particles. This collapse creates regions of cor…
Reaction-limited sintering in nearly saturated environments
Benny Davidovitch, Deniz Ertas, Thomas C. Halsey
We study the shape and growth rate of necks between sintered spheres with dissolution-precipitation dynamics in the reaction-limited regime. We determine the critical shape that se…
Ripening of Porous Media
Benny Davidovitch, Deniz Ertas, Thomas C. Halsey
We address the surface tension-driven dynamics of porous media in nearly saturated pore-space solutions. We linearize this dynamics in the reaction-limited regime near its fixed po…
Granular gravitational collapse and chute flow
Deniz Ertas, Thomas C. Halsey
Inelastic grains in a flow under gravitation tend to collapse into states in which the relative normal velocities of two neighboring grains is zero. If the time scale for this grav…
Stability of Monomer-Dimer Piles
Deniz Ertas, Thomas C. Halsey, Alex J. Levine +1
We measure how strong, localized contact adhesion between grains affects the maximum static critical angle, theta_c, of a dry sand pile. By mixing dimer grains, each consisting of…
