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.

The article deals with the issues of dispersion of heterogeneous liquids by spray nozzles in order to divide them into components. The influence of various parameters on the size of the droplets obtained is investigated. For the mathematical description the probabilistic approach is applied, which allows to obtain a differential function of the particle size distribution, which can form the basis of the engineering method of calculation of this class of separators. An expression for determining the average value of the angular velocity of the internal flow is compiled. These dependences allow us to calculate the most probable value of the angular velocity corresponding to the decay of complex drops into secondary ones, which are the drops of the initial liquids.
