The interfacial area per unit volume is one of the key parameters for the design of multiphase reactors. In this work a population balance approach is applied to calculate the interfacial area density in a bubble column. The resulting transport equation for the arithmetic bubble volume is coupled with the balance equations for mass and momentum. In addition the physical absorption of the gas ph...
