Abstract

The primary objective in this study is to numerically investigate the tangential velocity influence by center-bodies of plenum chamber in swirling fluidized bed (SFB). A numerical simulation using CFD package software was conducted with 3 hub geometrical designs (empty hub, full cylindrical hub and half cylindrical-half frustum) via plenum chamber depths (175 mm, 350 mm & 525 mm). In this study, 60 blades with 15° horizontal inclination were used. Distributor pressure drop and uniformity of flow at the distributor is set as performance criterion, which analyzed using a statistical analysis, i.e. mean and standard deviation. High tangential velocity at the interrogation area will tends a tremendous swirl flows and produce low pressure drops to ensure minimal energy consumption in the system. From this investigation, it shows that the empty hub geometries via 525 mm of plenum chamber depth offers a good balance in the required of airflow performance characteristics in a SFB.
