Abstract

The current stage in the development of agricultural production in livestock is characterized by the extensive use of pipeline transport to move the forage masses, which are related to non-Newtonian fluids. Production experience and scientific work on the study of hydrotransport systems showed that this method of transportation is the most economical and promising, it has high reliability of structural elements, improves sanitary and hygienic working conditions and makes it possible to fully automate the transportation process. The complex nature of the transportation of mixtures has not allowed to create a unified theory of hydrodynamic calculation of their parameters to date, therefore, various models are used for theoretical investigation of the nature of motion. To select a particular model, it is always important to correctly classify viscous semiliquid media with respect to hydrodynamics. Therefore, the article did not set out the specific goal of choosing a method for studying non-Newtonian systems, but solved the problem of their classification by known defining characteristics. The proposed classification does not pretend to be exhaustive in terms of the physical and chemical nature of the fluid, especially their combinations, but it covers almost all the anomalous phenomena that occur in the fluid during its transportation and helps to select a quantitative method for calculating the transporting fluid. The classification of non-Newtonian fluids with respect to their hydromechanics is based on the dependence of the shear stress on the shear gradient. For this dependence, each type of liquid is considered. The developed classification scheme further promotes a more complete account of the rheological properties of high-viscosity liquids during their transportation through pipes and facilitates the development of quantitative calculation methods.
