“…When dimensionless values are introduced, the channel height -H is taken as the length scale, and the average flow rate -at the channel inlet is taken as the velocity scale. For the numerical study of the problem posed, the system of Navier-Stokes equations averaged over Reynolds is used, taking into account the interaction between the phases [3]. The system of equations does not take into account the forces due to the effects of turbulent migration, Sefman, Magnus (lift force) and Coriolis [4].…”

Due to the occurrence of failures are divided into design, production and operational. Structural failures occur due to imperfection or violation of the established rules and (or) norms for the design of an object. Production - arise as a result of improper assignment of technological processes for the manufacture or restoration of parts and assembly of a car or are the result of a violation of the accepted technology, unsatisfactory quality of the material of parts or coatings applied to them, the use of insufficiently accurate measuring instruments, failure to meet technical requirements for the manufacture and assembly of elements, as well as the manufacture and assembly of elements and the object as a whole. In the article, basic information about the principles of calculations for solving a system of multiphase Navier–Stokes equations using the control volume method is provided. It is shown that the relationship between velocities and pressure is found using the procedure of SIMPLE. For the numerical solution of this problem, the McCormack scheme was applied. A comparison has been made between each other and with the experimental data. For turbulence, the Spalart–Allmares model was used. And also in the work the movement of sedimentary fluid in different diameters and different Reynolds numbers was studied.

Analytical methods exist to solve the problems of hydromechanics and heat transfer, but it is not possible to obtain the solution to some inhomogeneous and nonlinear problems of hydromechanics and heat transfer by analytical methods. The solution to such problems is carried out using numerical methods. Currently, there are many textbooks and monographs on numerical methods for solving problems of hydromechanics, thermal conductivity, heat and mass transfer, and others. The article presents the results of a numerical study of the flow structure in the flow around a flat plate. The calculations are based on the numerical solution of a system of nonstationary equations using a two-fluid turbulence model. For the numerical solution of these problems, schemes of the second and fourth order of accuracy were applied. The control volume method was used for the difference approximation of the initial equations, and the relationship between velocities and pressure was found using the SIMPLE procedure. To confirm the correctness of the numerical results, comparisons were made with each other and experimental data.

“…The purpose of this work is to model two-phase flow in centrifugal cyclones and compare the efficiencies of single SCN-50-800x1 and group SCN-50-400x4 cyclones with the same productivity of 4500 m3/h; parameters and dimensions of the cyclones can be found on the Internet. Modeling of aerodynamic processes of two-phase flow inside dust collectors was carried out based on the Comsol Multiphysics 6.1 software package, where the threeparametric v 2 -f turbulence model was used [9][10]. To study the flow dynamics, consider a system of hydrodynamic equations.…”

Centrifugal cyclones are devices used to separate solids or liquids from gas streams using centrifugal forces. They are widely used in various industrial processes, as well as for purifying air and gases from contaminants. The work carries out numerical modeling and study of the efficiency of single cyclone SCN-50-800 and group cyclone SCN-50-400x4. The study was carried out in the engineering software package Comsol Multiphysics 6.1 using the Flow Simulation add-on, designed for modeling hydrodynamic processes. The v2-f model, which is very often used in swirling flows, was chosen as the turbulence model. The computational experiment was carried out at the same productivity of 4500 m3/h. Based on the obtained numerical data, it is shown that the efficiency of group cyclones is significantly greater than that of single cyclones.
