摘要: This paper presents comparisons between experimental measurements and unsteady threedimensional numerical simulations performed by an unstructured parallelized CFD multiphase flow code of elutriation transport mono-dispersed glass beads type B A/B in a fluidized bed. These show satisfactory agreement predictions. The results also strong dependence on the mesh size, especially for fine particles. A model accounting influences mesoscales structures overall bed hydrodynamics, which are not resolved coarse simulations, is applied. Results obtained with improvements dense even step.
