MODELING DROPLET EVOLUTION ON A POROUS PARTICLE AS MICRO-SCALE PROCESS IN FLUIDIZED BED SPRAY DRYING

摘要：

　　In a fluidized bed spray drying process,formation of agglomerates has been recognized to be controlled by several micro-scale discrete interactions between particles and binder droplets.Among these interactions,we focus on the behavior of the binder droplet after its contact with the porous particle.This study presents a pore network model that accounts for three main mechanisms controlling the evolution of a liquid droplet: evaporation from droplet surface,capillary flow into the dry particle,and evaporation from the wet particle surface.
