A New Comprehensive Model and Simulation Package for Fluidized Bed Spray Granulation Processes

The model introduced in this paper makes it possible to calculate the expected product and bed material particle size distribution, as well as the dynamic behavior of process state variables. It was integrated in the developed software package FBSim and it could be shown that even a complex process like the fluidized bed spray granulation can be simulated in its dynamic behavior, if existing models are extended and coupled. The implemented model achieves a coupled solution of the population balance and heat and mass transfer equations.
