The impact of local phenomena on mass transfer from single bubbles and bubbles rising under swarm conditions with the bubble diameter and the viscosity as variation parameters is investigated by using laser‐induced fluorescence. It is reported that the wake shedding frequency of ellipsoid bubbles is decisively responsible for the convective mass transfer. A novel mass transfer correlation is developed considering the Strouhal number and swarm conditions.
