## Abstract Fluidization of binary mixtures of particles belonging to group B of the Geldart classification of powders was studied. Beds tested were prepared by mixing in different proportions particles with almost equal density (β2,500 kg/m^3^) and dissimilar size (125 ΞΌm silica sand and 500 ΞΌm gl

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
## Abstract The steadyβstate segregation and dispersion of a binary system of particles in a liquidβfluidized bed was investigated. One of the species had a density of 1,600 kg/m^3^ and the other 1,900 kg/m^3^, and both exhibited a narrow size range of 1.00 to 1.18 mm. A generalized model for descr
