Mixing hi monosized particles and binary mixtures of solids in three-phase fluidized beds is investigated by means of a non-invasive Radioactive Particle Tracking technique (RPT). Pulses of particles at different column heights are constructed from the trajectory of a single radioactive tracer whose
An inviscid model is developed to describe gross solid circulation and gas backmixing in axisymmetric fluidized beds. Two distinct cases arc shown to arise: (1) interstitial gas moves upwards everywhere; and (2) interstitial gas circulates giving rise to loop formation in an annular region near th
