Simulations of collision times in gravity driven granular flow
arXiv:cond-mat/0609330 · doi:10.1209/epl/i2006-10286-2
Abstract
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 power-law 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 simulation and experiments on the exponent of the collision time power-law distribution.
