The article discusses the basic model of the formation of an emulsion layer on a rotating cylinder. Special attention is paid to the study of the influence of various parameters on the internal characteristics of the emulsion formation process. A mathematical description of the displacement layer is given and functional dependencies between the parameters characterizing the emulsion formation process are derived. Based on experimental data, the qualitative influence of "internal" and "external" factors on the formation of the emulsion layer has been studied. The result of the study were graphs, analyzing which the following conclusions can be drawn. An increase in the viscosity of the emulsion leads to a decrease in such parameters as the boundary of the fracture region of a more viscous liquid layer adjacent to the surface of the rotating cylinder, the viscosity of the emulsion in the transition layer, but there is an increase in the consumption of the emulsion. It is also established that the growth of the complex of "external" parameters leads to a decrease in all internal parameters during the formation of the emulsion. The research conducted in the article will help to take into account the obtained dependencies when calculating the operating and design parameters of devices.
