Direct numerical simulation of the CO2CO2 transfer from spherical bubbles to NaHCO3NaHCO3 and Na2Na2CO3CO3 aqueous solutions with clean and fully contaminated interface

This work deals with the quantification of the bubble-liquid CO2CO2 transfer rate coupled with chemical reactions in the liquid phase. A two-dimensional axisymmetrical model is developed. The numerical simulations are validated without chemical reaction. The validated numerical procedure is used to study the enhancement influence of chemical reactions on the bubble-liquid mass transfer rate. Moreover, the results of this study are compared with classical uni-dimensional approaches and excellent comparisons are observed.
