Abstract
The hydrodynamic properties and mixing pattern in gas -solid fluidized beds are dependent on many parameters, such as gas properties, solid properties, gas entrance conditions, and distributor geometry. The fluidized bed is seen as a mass oscillating on top of an air-filled cavity called plenum chamber.
.Ā TheĀ swirlingĀ fliudised bed dryer plenum chamberĀ sectionĀ playsĀ aĀ vitalĀ role Ā inĀ distributingĀ theĀ fluidĀ beforeĀ itĀ entersĀ theĀ distributor. The quality of distribution affects theĀ performanceĀ ofĀ theĀ fluidizedĀ bed.
Most researchers who investigate the hydrodynamics of fluidized beds did not take the effect of the plenum into account.Ā Here fluidization enhancement of a swirling fluidized bed dryer with plenum chamber and distributor plate is taken into account and remodification is done.
