Hydrodynamic Studies on Conventional and Tapered Fluidized Bed

In this project the determination of maximum pressure drop, minimum fluidization velocity, minimum bubbling velocity and fluidization index for various powders are to be studied using a conventional cylindrical bed and a tapered bed. Tapered beds have a velocity gradient along the axis unlike conventional beds. They have been used as an alternative to conventional cylindrical beds to deal with problems such as slugging. Initially air at ambient conditions (310 K) is to be used as the fluidizing medium. High temperature studies will also be carried out using a High temperature fluidized bed (Air temperature up to 1173 K).
