Effect of surface-active agents on the multiphase flows

Surfactants are substances whose molecules adsorb on the interfacial surface and influence the behaviour of multiphase systems (especially gas-liquid dispersions). In the case of biosurfactants (e.g. proteins, peptides), the mechanism of adsorption to the interface is not sufficiently described, and therefore it is difficult to predict their influence on the behaviour of the entire system. The aim of the research is to study the mechanism of adsorption of surfactants and biosurfactants on the bubble interface and their projection to hydrodynamics and mass transfer in bubbly flows.
