Numerical Calculation of the Flow Field in a Bubble Column Considering the Absorption of the Gas Phase
نویسندگان
چکیده
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 phase is considered. The calculations are performed for three dimensional, instationary flow fields in cylindrical bubble columns using the Euler-Euler approach. For the calculation the commercial code CFX-4 is used.
