In this contribution coupled CFD-DEM simulations of a three-dimensional prismatic spouted bed for coating purposes were performed. The simulations were validated by means of pressure drop fluctuations and flow pattern with respect to experimental data. In order to increase the spouting stability, draft plates were inserted into the process chamber. To investigate the influence of flow stability on coating quality, droplets were injected in a post-processing step and deposited on colliding particle parcels. By means of that tool the time-dependent cumulative distribution function of the particle liquid loading was calculated and compared for different process configurations.
