Abstract:

The liquid-solid counter-current fluidization processes in an extraction column were numerically simulated based on the particle trajectory model of Eulerian-Lagrangian method. The simulation approach was previously validated by experiments. A power function correlation between the dimensionless slip velocity Uslip/Ut and hold-up fraction was proposed, and the operational zone in the countercurrent fluidization process was determined. Moreover, the simultaneous countercurrent fluidization of multi-particles with different diameters was also simulated. The comparison between the simulation results and the calculating values of the multiparticle free sedimentation model based on non-interference assumption shows considerably consistent, which also verified the reliability of the simulation approach used in present work.
