Introduction to Fluidization - AIChE
Nov 21, 2014 · particle density, ε is the bed voidage (i.e., gas volume frac-tion), ρ g is the gas density, and ρ bulk is the bulk density. The gas density is minimal compared to the bulk density and can be disregarded in Eq. 1. The minimum fluidization velocity, mf u, can be estimated for spherical particles by first calculating the Archimedes number, Ar ...
