Abstract. Modelling the pulp fluid and its interaction with both the charge and the mill structure is an interesting challenge. The interaction is normally modelled with a combination of CFD and DEM where the DEM particles (grinding balls) create the structure through which the fluid penetrates and in its turn creates forces on the grinding balls.
