“…It should be stressed here that the FT-IB method presented in this paper differs from the hybrid volume of fluid-DP model developed by Fan and co-workers (Li et al, 1999(Li et al, , 2000(Li et al, , 2001Zhang et al, 2000a,b) and the hybrid FT-DP model by van Sint Annaland et al (2005) for dispersed gas-liquid-solid three-phase flow. The FT-IB model presented in this work differs in the sense that the details of the flow at the level of the particles are fully resolved.…”

“…Since then, there have been several works reported in scientific literature [20][21][22][23]. Liquid-solid interactions have been studied in case of gas bubble formation in a gas-liquid-solid system [24][25][26]. Similar studies have been reported in case of gas and liquid fluidized beds in the bubbling regimes where a rigorous two way coupling framework has been introduced to explain the fluid-particle interaction [27,28].…”

A Multi-Scale Hybrid CFD-DEM-PBM Description of a Fluid-Bed Granulation Process

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 the liquid binder on the fluidized powder bed. The fluid flow field has been solved implementing CFD principles and the behavior of the solid particles has been modeled using DEM techniques whereas the change in particle size has been quantified with the help of PBM. The liquid binder droplets have been modeled implicitly in DEM. A detailed understanding of the process aids in the development of better design, optimization and control strategies. The model predicts the evolution of important process variables (i.e., average particle diameter, particle size distribution (PSD) and particle liquid content) over time, which have qualitative similarity with experimentally observed trends. The advantage of incorporating the multi-scale approach is that the model can be used to study the distributions of collision frequencies, particle velocity and particle liquid content in different sections of the fluid bed granulator (FBG), in a more mechanistic manner.
