Beside the subject of bubbles and drops as an area of intense study for many years, the attention is naturally focused on the problem of fluid particle deformation. One of the earliest analysis in this field goes as far back as the 1930’s when Taylor (1934) treated the deformation of drops in linear shear and hyperbolic flows by means of the domain perturbation techniques. In most studies in this area, the matter of drop deformation was found to require special attention because of its well-known influence on the dynamics of such objects and on some processes like extraction, for example. Other areas of such studies application are the emulsion formation, where one fluid phase must be dispersed in another fluid, and the design of efficient mixing devices. The problems of oil recovery, where oil drops must be displaced by water in porous rock, are also related to the drop deformations.
