Simulation of fluidized bed granulation

This video shows a full-coupled CFD-DEM simulation of a fluidized bed granulation process. A liquid-solid mixture is sprayed into the granulator (see droplets in magenta) from a nozzle. The liquid and solid species are deposited onto the carrier particles and, partially, onto the granulator walls. The product quality (between 0 to 1) measures the coating/granulation level of the carrier particles. Finally, the temperature field changes dynamically due to the heating from the fluidization air and the cooling due to the liquid evaporation.
