ABSTRACT
The influence of surface active agents (surfactants) on the deformation of droplets and the structure of the surrounding flow field is an active research area with numerous applications. The convective transport of surfactants induced by the flow field generates a local accumulation resulting in a nonuniform concentration of surfactants at the liquid-fluid interface. The appearing Marangoni forces may lead to a destabilization of the interface with essential consequences for the flow structure. This is a complex process, whose tailored use in applications requires a fundamental understanding of the mutual interplay.
