4. Fluidization regimes: dense bed and circulating bed
4.1 Homogeneous and heterogeneous fluidization regimes
The fluidization range for particles with a given Archimedean number corresponds to all empty-barrel gas flow velocities U between Umf and Ut, i.e. Reynolds numbers between Remf and Rept. This range is wider the higher the ratio Rept/Remf.
Variations in this ratio, as a function of Ar, can be plotted for different values of εmf (figure 4).
The smaller the Archimedean number of the solid/gas system, the wider...
