Hydrodynamics of turbulent bed contactors. 2. Pressure drop, bed expansion, and minimum fluidizing velocity

Correlations for pressure drop, bed expansion, and minimum fluidization velocity in turbulent bed contactors are presented. They show the importance of the flow regime in which the bed is operated. The characteristics of each operating regime are discussed and compared with the characteristics of pa...

Zusammenfassung:Correlations for pressure drop, bed expansion, and minimum fluidization velocity in turbulent bed contactors are presented. They show the importance of the flow regime in which the bed is operated. The characteristics of each operating regime are discussed and compared with the characteristics of packed-bed columns.
