Specification of model representations of complex transfer processes in liquid emulsions based on mechanisms of the basic physical phenomena (MВPP) is considered in this paper. For the representation of the complex models of the transfer processes in a generalized form a correspondence of dimensionless similarity criteria and the most simple, basic physical phenomena are used. With a lack of complete mathematical models they are replaced by a set of such basic phenomena which express physical content of a complex process. Regressive relationships between the corresponding similarity criteria are evaluated on the basis of the experimental measurement data. As a result, a formal statistical analysis is filled with an objective physical content in accordance with the nature of the MВPP.

“…Rozentsvaig (1981) pointed out that the contribution of viscous shear may be significant to droplet breakage in pipe flows, and he modified the model in an attempt to reconcile it with the published experimental data. There is evidence that this particular power law form is not applicable in low-energy flows and some pipe flows (which are neither isotropic nor homogeneous).…”

“…Therefore, the hydrodynamic model of unstable emulsions needs to be complemented by discrete models of population balance (DPB). They detail the composition and relationship of the physical phenomena due to the presence of the dispersed phase (Rosentsvaig and Pergushev [8], Rosentsvaig [9,10]). However, the formation of droplet size spectrum depends on the flow conditions of emulsion, which are specified by the hydrodynamic model.…”
