“…In recent years, experiments focused on single mass transfer with rising bubbles to obtain a better understanding of local effects [1] such as wake shedding, bubble contamination [2][3][4][5][6], pH influence [7] and local mass transfer [1,[8][9][10][11]. With the aid of Computational-Fluid-Dynamics (CFD) simulations, local hydrodynamics can be resolved and give further information in respect to local modeling of mass transfer [12][13][14][15][16]. Koynov and Khinast [17] investigated the effect of hydrodynamics on chemically reacting bubble flows using Direct Numerical Simulations (DNS).…”

“…To handle the interfacial jump discontinuity numerically is a challenging task. Volume of Fluid (VOF)-based simulations of mass transfer across deforming interfaces have been reported in [1] and in [2,3]. In the latter papers, transfer of oxygen from air bubbles rising in water or aqueous solutions has been simulated, taking into account the realistic jump discontinuity of the oxygen profiles at the interface.…”
