Abstract: The impact of local phenomena on mass transfer from single free-rising gas bubbles with and without a superimposed chemical reaction was investigated using laser-induced fluorescence and particle image velocimetry. This paper discusses a novel calculation method for mass transfer rates using local concentration and velocity fields. Qualitative and quantitative results for the impact of a superimposed sulfite–sulfate reaction on oxygen mass transfer are also presented.
