This study experimentally examines the hydrodynamics of packed and fluidised beds in terms of pressure drop, bed expansion and minimum fluidisation velocity in tube sizes with inner diameters of 0.8, 1.2 and 17.1 mm.

Experimental minimum fluidisation velocity results compare well with the literature and theoretical values calculated from existing models.

Investigations into minimum fluidisation velocity, solids flux, gas bypassing between reactors, and pressure profiles of the system have been undertaken, the results of which are presented and discussed.
