Flow through Fluidized Bed

  1. Air at 1 atm and 20 degree C flows through a packed bed. The diameter of a sphere in the bed is 1 mm and the density of it is 2.4 g/cm3. The bed porosity is 0.4. The diameter of the bed 2.75m and the height is 2.75m.The viscosity of the air is 1.81*10-5. Find the minimum fluidization velocity and the minimum fluidization mass flow rate.
  2. From literature, collect information on applications of fluidized bed in chemical engineering processes.
