Cellular-automaton model for segregation of a two-species granular flow

Abstract

A cellular-automaton model is presented for the segregation of a granular flow. The need for such a model arose originally from consideration of a problem related to the ferro-alloy industry. The flow consists of particles of two different sizes, which in this specific industrial application are lumps of ore and coal or coke. It is known from experiments [S. A. Halvorsen, S. E. Remnes, and P. Hyldmo (unpublished)] that these particles show different mobilities under different circumstances. This effect is incorporated in our model via the inclusion of a ``hydrostatic pressure'' term.
