Collision statistics of driven granular materials.
We present an experimental investigation of the statistical properties of spherical granular particles on an inclined plane that are excited by an oscillating side wall. The data is obtained by high-speed imaging and particle tracking techniques. We identify all particles in the system and link their positions to form trajectories over long times. Thus, we identify particle collisions to measur...
متن کاملSimulations of collision times in gravity driven granular flow
– We use simulations to investigate collision time distributions as one approaches the static limit of steady-state flow of dry granular matter. The collision times fall in a powerlaw distribution with an exponent dictated by whether the grains are ordered or disordered. Remarkably, the exponents have almost no dependence on dimension. We are also able to resolve a disagreement between simulati...
متن کاملAvalanche Statistics of Driven Granular Slides in a Miniature Mound
We examine avalanche statistics of rainand vibrationdriven granular slides in miniature soil mounds using experimental and numerical approaches. A crossover from powerlaw to non power-law avalanche-size statistics is demonstrated as a generic driving rate ν is increased, due to diminishing timescale separation (∼ ν) between stress buildup and release. For slowly-driven mounds, the tail of the a...
متن کاملShear-driven size segregation of granular materials: modeling and experiment.
Granular materials segregate by size under shear, and the ability to quantitatively predict the time required to achieve complete segregation is a key test of our understanding of the segregation process. In this paper, we apply the Gray-Thornton model of segregation (developed for linear shear profiles) to a granular flow with an exponential shear profile, and evaluate its ability to describe ...
متن کاملRandomly driven granular fluids: collisional statistics and short scale structure.
We present a molecular-dynamics and kinetic theory study of granular material, modeled by inelastic hard disks, fluidized by a random driving force. The focus is on collisional averages and short-distance correlations in the nonequilibrium steady state, in order to analyze in a quantitative manner the breakdown of molecular chaos, i.e., factorization of the two-particle distribution function, f...
