The research illustrates that a laminar pulsating flow of viscous two-phase media in a cylindrical pipe is studied. On the basis of numerical simulation, the main parameters influencing the formation of the structure of a two-phase flow in a pipe are determined.One of the most important problems in the study of the mechanics of multiphase media is the construction and selection of hydrodynamic models for specific types of mixture flow. At the same time, it is very important to avoid unjustified complication of models, since otherwise they may be unsuitable for applications. At the same time, neglecting phenomena that significantly affect processes can make it too rough, not only not providing the required accuracy of calculations, but also not reflecting the main features of the processes.Similar processes are often observed in the food industry, in the processes of extraction, dissolution, drying, crystallization, as well as when cleaning the internal surfaces of equipment pipes from deposits and sediments. Fundamental studies of such issues require the creation and selection of hydrodynamic models that really reflect the physics of phenomena in the mixture, the development of universal algorithms and the use of high-speed computing systems to solve these problems, allowing a deeper study of the true picture of the processes under consideration. Although a large number of scientific papers have been published on the hydrodynamics of pulsating flows, however, many issues have not yet been studied enough. These include, for example, the unsteady motion of pulsating flows of multiphase media in pipes with permeable and impermeable walls. Separate works and theories of the study of these processes, as a rule, are based on the use of simplified models.
