Iron Ore Pellet Drying

Drying of a bed of iron ore pellets is therefore considered by modeling a two dimensional discrete system of round pellets The system is divided by modified Voronoi diagrams and the convective heat transfer of hot fluid flow through the system including dispersion due to random configuration of the pellets is modeled The results show that the
