A comprehensive interpretation of solid layer inversion in liquid fluidised beds

Intensification of mass transfer in liquid fluidized beds with inert particles

“…In contrast to several authors [5,19], no complete layer inversion phenomenon is observed. This discrepancy of mixing states can be attributed to the different particle properties, e.g.…”

Applications of polydisperse sedimentation models

“…Complete mixing and bed inversion of bidisperse suspensions have long been of particular interest [37,64,65,66,67]. Berres et al [62] established compatibility conditions for bidisperse systems and later [63] extended the analysis to tridisperse and higher discrete polydisperse systems.…”

“…Fluidization of a bidisperse suspension. Next, we present a new simulation of the fluidization of a bidisperse suspension studied by Moritomi et al [66]. The relevant Figure 4.…”

“…We consider a tridisperse suspension with particles made of the same material (ρ 1 = ρ 2 = ρ 3 = 1800 kg/m Figure 3. Simulation of the settling of a bidisperse suspension with parameters chosen according to Moritomi et al [66]. The solid and dotted lines are Lagrangian paths of species 1 and 2, respectively.…”
