Abstract
The DEM (discrete element method) simulations for cohesive fine particles were carried out with the representative particle model. In order to simulate the process of surface improvement the liquid bridging force which depends on temperature was considered. From the calculations, hot fluid occupied the central region near the inlet of particles. On the other hand, cool fluid occupied the downstream region. Agglomerated particles took place in the central region near the inlet of particles and they were maintained in the downward region where the temperature was low. This was caused by the condition of cohesive force corresponding the solidification of liquid bridging.
