Abstract
1. The deformation of dispersed particles of twophase liquid systems investigated by the small-angle light scattering method corroborates the fact that the viscosity ratio between the dispersed and continuous phases is important. Under experimental conditions the deformation is observed atη′/η < 4–6 and it is maximum asη →η. The drop axial ratio increases with shear rate and drop volume, and decreases with increasing interfacial tension. 2. In principle, the shape of drops deformed in the flow can be fixed by converting the continuous medium into gel state. The resulting anisotropic gel filled with anisodiametrical liquid drops oriented along the direction of shear can be called as capillary-structure gel which are anisotropic by their optical and mechanical properties. 3. The structure of two-phase liquid systems in the flow is shown to strongly depend on the lifetime of anisodiametrical dispersed drops exhibiting high degree of asymmetry. The dynamic equilibrium, breakdown of liquid cylinder ⇄ coalescence of drops, is also of great importance. When the dispersed phase passes from liquid to gel state, the dynamic equilibrium shifts towards the breakdown of liquid cylinder due to suppressed coalescence of dispersed particles in the gel state. 4. The shape of deformed dispersed drops of two-phase systems can be fixed by converting them into a gel state provided the lifetime of these anisodiametrical particles is not lesser than the transition time.
