Abstract
We study the turbulent stationary motion of a mixture in a horizontal cylindrical pipe, taking into account the formation of a concentration field of the second dispersed phase that is not uniform over the cross section, and estimate the transporting ability of the flow. The article has developed a model for the movement of a two-phase mixture in a horizontal cylindrical pipe, taking into account the uneven distribution of the concentration of the second phase over the flow … Also, in this model of mixture motion, the coefficient of the force of interaction between the phases is determined depending on the concentration distribution. The problem is solved by a numerical method. Investigating the numerical results of the problem, the nature of the formation of the velocity field at various values of the flow saturation with solid particles is revealed and makes it possible to assess the account of the size of these particles, taking into account the turbulence of the flow. The implementation of the developed mathematical models and recommendations will make it possible to predict the transporting ability of a two-phase flow in pressure systems, and helps to find solutions with spatial hydrotransport and irrigation and drainage systems.
