Packed Bed/ Fixed Bed Fluidzation

Packed Bed Fluidzation

A fixed or packed bed refers to a bed of stationary particles residing on a perforated grid, through which a gas flows. A fixed layer of small particles or objects arranged in a vessel to promote intimate contact between gases, vapors, liquids, solids, or various combinations thereof; used in catalysis, ion exchange, sand filtration, distillation, absorption, and mixing. 


Є = Void fraction of the bed
X = Sphericity
µ = Dynamic viscosity
Pg = Density of the gas
U = Superficial gas velocity
