Swirling Fluidized Bed (SFB) is one of the fluidized bed systems that has the potential to be widely use in mineral processing, power generation and chemical industries. High performance can be achieved by using an annular bed and inclined injection of gas through the distributor in SFB. A numerical simulation Computational Fluid Dynamics (CFD) and experimental work with Particle Image Velocimetry (PIV) has been used to investigate physical parameters that influenced the type of plenum chamber, the distributor pressure drop and the uniformity of tangential velocity distribution. The study...
