The problem of increasing the reliability and durability of hydrotransport facilities is one of the most important national economic tasks. The formation of the concentration field of the second dispersed phase, which is nonuniform over the cross section, is studied by the turbulent stationary motion of the mixture in a horizontal cylindrical pipe and the transporting ability of the flow is estimated. The article proposed a mathematical model and a method for calculating the concentration field of solid particles along the depth of the flow using information technologies, where the formation of the concentration field is first determined through the size of solid particles when a two-phase mixture moves in a horizontal cylindrical pipe. 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 using the integrated system for mathematical calculations MathCAD. Investigating the numerical results of the problem, the nature of the formation of the concentration field at various values of the saturation of the flow with solid particles and which makes it possible to estimate 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 help to find solutions for spatial hydrotransportation and irrigation and drainage systems.

In the agricultural sector of the Republic of Uzbekistan, a tendency to automate production and business processes can be seen. Agriculture automation helps to significantly reduce the amount of manual labour, while increasing work efficiency. It is possible to single out the following practical advantages of introducing automation in the agricultural sector: it becomes possible to manage production, technological and business operations in an optimized and effortless manner; the competitiveness of the goods is growing through improving the quality and reducing the cost; the productivity of agricultural enterprises increases; cost minimization leads to a drop in the cost price of manufacture of products, and a manufacturing organization can offer the products at a price, which is affordable for the buyer and at the same time profitable for the manufacturing organization. The use of modern technologies for the ‘intellectualization’ of agriculture makes it possible to preserve and restore the beneficial properties of groundwater and soil; to provide environmentally safe and effective pest control; to remotely monitor compliance with the certification requirements of organic agriculture. It is necessary to automate not only production, but also business processes in the agricultural sector. The main goal is to increase the productivity of enterprises, minimize the number of errors associated with the ‘human factor,’ and reduce the amount of ‘manual labour’. The article substantiates a systematic approach to the formation of the information space of an agricultural enterprise, taking into account the needs of all participants in process management, the choice of a software and hardware platform and methods for automating the software development process.

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.
