Simulation of commercial scale tablet press feed system with a coupled CFD-DEM model.

CFD-DEM simulation of a fine, poly-disperse pharmaceutical powder in a closed tube. It can be clearly seen that size segregation is caused by the counter-current airflow which is induced by the particle stream falling downwards. This use case is inspired by Kocevar et al. (2015).

This video shows a simulation of solid-liquid mixing in stirred tank. A semi-implicit immersed boundary method has been used to solve the fluid flow due to the rotating geometry. The CFD-DEM coupling, however, is of the unresolved type. Please, refer to the following publication for further information: Blais, B. et al. (2016). Development of an unresolved CFD–DEM model for the flow of viscous suspensions and its application to solid–liquid mixing.
