Abstract
In this study, the role of hydrodynamics of the dense bed on the particle convection is outlined. The existing models in the literature suggest a constant decrease of particle-wall contact time with an increase in the gas velocity. However, it has been experimentally shown that the contact time increases both in bubbling and turbulent regimes upon increasing the gas velocity. A comprehensive model is developed to represent such a trend and improve agreement with experimental data presented in literature. Comparison of predicted results with the experimental data from the literature confirms the validity of the present model for the dense bed region of fluidized bed of sand particles.
