Abstract

A novel distributor termed as the sloped distributor is introduced and studied for its aerodynamics and hydrodynamics with Geldart type D particles in a swirling fluidized bed system. The aerodynamics study involves a validated numerical simulation to characterize the effect three sloping angles of 10°, 13.5° and 15° in comparison to existing flat distributor (0° sloping angle). As for the hydrodynamics study, four extra-large Geldart type-D particles having diameters of 4.85 mm, 5.81 mm, 7.70 mm and 9.84 mm were investigated for four bed weights of0.5 kg, 0.75 kg, 1.0 kg and 1.5 kg (corresponding to four bed heights). From the aerodynamics study, it was found that the sloping distributors improve air velocity distribution significantly and provide a force component in the radially inward direction which counterbalances the centrifugal force generated by the swirling motion.
