Hydrodynamics and reaction process phenomena in bubble column reactors are complex and intrinsic interlinked and not fully understood. To obtain a better understanding, for the first time, a multiphase Euler-Euler solver is developed and validated to experimental data for the absorption of carbon dioxide in water offering the possibility of detailed temporal local and spatial analysis. The open source CFD tool OpenFOAM� with the multiphase solver multiphase Euler Foam is extended: (i) an absorption model was implemented, enabling absorption from different bubble size or phases to the liquid (ii) a chemical reaction model accounts for any number of reactions. The extensions were validated based on literature data and own experimental results at higher pH-value. The simulation results show a satisfactory agreement to experimental and simulative data from literature as well as to own experi.. View More»
