Numerical Study Of Laminar Flow In A Suddenly Expanding Channel, Murodil Madaliev
Numerical Study Of Laminar Flow In A Suddenly Expanding Channel, Murodil Madaliev
Scientific-technical journal
The article presents the results of a numerical study of the flow structure in a flat channel in the zone of its sudden expansion in the form of a ledge. The calculations are based on the numerical solution of a system of non-stationary equations using Navier-Stokes. The results of the longitudinal velocity profiles in various sections of the channel after the ledge are obtained. For the difference approximation of the initial equations, the control volume method was used, and the relationship between velocities and pressure was found using the SIMPLE procedure. For the numerical solution of this problem, the McCormack …
