Hybrid drops are comprised of two or more immiscible phases. They occur in various natural and technological processes and environments, e.g. the atmosphere, liquid membranes and liquid bi-layers, direct contact heat and phase separation processes. The overall objective of this research was to enlighten the problem of the dynamics of hybrid drops by developing mathematical methods to study the behavior of an aggregate composed of two drops in an arbitrary intersection angle in the presence of Marangoni effect for the cases of none and moderate deformable surfaces. In order to achieve the research goals analytical and numerical methods were being used. The results of the research should be useful for better understanding of the role of the Marangoni effect in natural and technological processes involving multiphase flows with a changing topology of the dispersed phase such as emulsification, liquid-liquid extraction, composite material processing, etc.
