Abstract (type = abstract)
A two-way coupled Computational fluid dynamics (CFD) – Discrete element method (DEM) model is developed using STAR-CCM+ for a top spray fluid bed granulator to study the effects of process parameters such as inlet air flow rate, temperature on the particle dynamics and the residence time in the spray zone. The framework relies on coupled CFD–DEM simulations to provide particle-level mechanistic information such as collision frequencies, particle flux and residence time of the particles in the spray zone. Particles of diameter 1 mm (Group B particles according to Geldart’s classification of powders) are considered for model development. To reduce the computational load, the particles are scaled by keeping the non-dimensional terms Archimedes, Reynolds’s numbers and the minimum fluidization velocity of the system constant. Passive scalar model is also used for Lagrangian phase to track the residence time of the particles within the spray zone. This model accurately predicts the effect of process parameters (inlet air flow rate, temperature) on the particle dynamics and the particle residence time inside the spray zone. This mechanistic data can be used in Population balance models (PBM) to model the rate processes such as agglomeration, breakage and consolidation.
