In many process engineering applications, the dynamics of gas‐liquid two‐phase flows plays a crucial role. The transfer of mass from the gaseous phase into the liquid phase is often a limiting step. This communication deals with the question how vortex structures, which are ubiquitous in engineering fluid flows, influence the transport processes of mass and momentum close to the interface. The question is approached by means of a methodical series of experiments with increasing optical access. By utilizing particle image velocimetry and laser‐induced fluorescence, detailed investigations of hydrodynamics and mass transfer are carried out.
