A correlation for interfacial area in co-current gas-liquid downflow through packed beds

Interfacial area in cocurrent gas-liquid downflow through packed beds is correlated taking into consideration the physical properties of the fluids and the power dissipation in the system. The correlation is tested with the experimental data covering a wide range in system variables including low and high porosity packings, the flow rates of the phases and their physical properties. © 1994 Springer-Verlag.
