Abstmct-The foundations and applications of the Kennedy and Bretton model for mixing and segregation in liquid fluidized beds containing two sizes of equal density particles are critic&y examined. Adirect method of solution that avoids all the difficulties and pitfalls of previous methods is present

The behaviour of liquid-fluid&d binary-solid mixtures can be represend by a '%omplete segregation model", where two superposed non-interacting zones am predicted to form. Deviations from this idealized situation may be predicted utilizing existing relationships for the total interaction force on a p
A new mechanism is proposed to interpret the phenomena observed in the liquid fluidization of the binary particle mixture. Two main factors, the bulk density and voidage fluctuation, are considered to determine the position of the layer of particles in the bed. The new model successfully explains th
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
