In continuous powder handling processes, precise and consistent feeding is crucial for ensuring the quality of the final product. The intermixing effect caused by agitators, which alters the powder’s bulk density, flow rate, and flow patterns, plays a significant role in this process, yet...
A multi-scale hybrid CFD-DEM-PBM description of a fluid-bed granulation process
| Contributor(s):: Sen, Maitraye, Barrasso, Dana Singh, Ravendra, Ramachandran, Rohit
In this study, a hybrid multi-scale model has been developed for a continuous fluid bed wet granulation process by dynamically coupling computational fluid dynamics (CFD) with a discrete element model (DEM) and population balance model (PBM). In this process, the granules are formed by spraying...
