The effects of vertical, sinusoidal vibrations on the fluidization behavior of a granular bed are studied, where we focus on the solid circulation rate and its dependence on the vibration parameters. To this end, an experimental study was performed i

To gain insight into the hydrodynamics of spout-fluid beds, an experimental and numerical study was carried out. Particle image velocimetry was successfully developed and applied to determine particle velocity profiles, whereas voidage profiles were

We have investigated by numerical simulation the density segregation of fine equal-sized bronze and glass particles subject to vertical vibrations. The model was found to be capable of predicting the two main segregation forms ("bronze on top" and "s

We have investigated the effect of air on the density segregation of fine, equal-sized bronze and glass particles under vertical sinusoidal vibrations by numerical simulation, using a hybrid granular dynamics-computational fluid dynamics model. We fi
