Numerical simulation of granular materials in a rotating tumbler

Horacio Tapia-McClung

Vol. 2 (2007), No. 8, 1431–1436
Abstract

Using a simple numerical model based on particle dynamics, we perform two-dimensional simulations of granular materials inside a rotating tumbler. Still in its first stages of development, the model can quantitatively reproduce some of the general behavior observed in these systems, both for monodisperse and binary mixtures. Work is currently being done to validate the model and obtain results that are directly comparable to experiments.
