In this paper a continuum model for the prediction of segregation in granular material is presented. The numerical framework, a 3‐D, unstructured grid, finite‐volume code is described, and the micro‐physical parametrizations, which are used to describe the processes and interactions at the microscopic level that lead to segregation, are analysed. Numerical simulations and comparisons with experimental data are then presented and conclusions are drawn on the capability of the model to accurately simulate the behaviour of granular matter during flow.
