Numerical investigation of multiphase flow in a channel

Abstract

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.
