“…The Nave-Stokes method has been widely used to determine the movement of solid particles, viscosity, and flow rate in hydromixed flow. The grapho-analytical method was used to determine the deformation caused by the movement of solid particles to hydrotransport systems, whether particles obey Archimedes' law in a suspended state and are in a state of tension [4,5,11,12].…”

“…The existing calculated dependencies of the main parameters of hydrotransport are based on the law of turbulent transfer of the solid phase with the flow of liquid, and the effectiveness of the process has been considered by many scientists in connection with the effect on the turbulent properties of solid particles [2][3][4][5][6][7][8][9][10][11].…”

The article examines the movement of solid particles, the hydraulic calculations of pipes in the process of movement, the classification of reducing the impact of solid particles on hydrotransport systems. The effect of solid particle magnification on flow rate, pressure loss, speed reduction as a result of the effect of internal friction forces of solid particles, friction in the flow of solid particle hydroarations, pressure loss as a result of the impact of Resistance Forces, internal corrosion process observed in the pipe, increased energy consumption were analyzed using the example of hydrotransport systems Recommendations have been made to solve the problems of speed reduction and pressure loss due to the movement of solid particles in the hydroaration flow through the modification method. The prior and subsequent movement of solid particles in a pipe modification is shown through comparison graphs. Information about the gossipol Tar selected as a modifier is provided.

Mathematical modeling of wastewater treatment facilities of transport enterprises

Wastewater is purified by mechanical, biological, physicochemical and chemical methods. Mechanical treatment plants are the main stage of treatment and remove most of the harmful substances contained in wastewater. The mechanical treatment facilities include a sand trap, a sump, a hydrocyclone, a grid, etc. Among them, the most common and basic design are sumps, which are divided into types according to design and function. In this article, a new mathematical model for calculating vertical sediments used in local treatment for small enterprises has been improved, and design parameters have been calculated. Theoretical studies of the proposed sump were carried out on the basis of molecular kinetic theory, and its accuracy was verified by the author in experimental tests. In the sump, an expression for the distribution of the concentration of suspended solids in wastewater was found. Thus, a filter structure with a filtration efficiency above 60% was created.
