AB - Since the fluidization curve of polydispersive materials has a transition area, the apparent and the total minimum fluidization velocity can be defined. Therefore, the dependence of the total entrainment flux upon the apparent and the total fluidization number were investigated. Experiments were performed in 200 mm diameter glass column, with mixtures of coarse and fine particles of silica sand as bed materials. 
The influence of bed material structure, fluidization number (apparent and total), bubble diameter and freeboard height are taken into consideration in the analysis of the experimentally obtained results for total entrainment flux.
