The axial profiles of the particle concentrations before and after the solid layer inversion were investigated in two-and three-phase fluidized beds containing binary solid mixtures.The marn column with 210 mm diameter and 1.8 m height was made of a half-tube acrylic resin.The binary solid mixture was composed of 3.2-mm polymer beads (ρs=l,280 kg/m3) and 0.385-mm glass beads (ρs=2,500 kg/m3) as lighter/larger parti cles and heavier/smaller particles, respectively.
