The EFFECT OF CHOICE OF INLET BOUNDARY CONDITIONS FOR THE Κ-Ε TURBULENCE MODEL

Abstract

An investigation into the effect of inlet boundary conditions choice on the solution of the time-averaged Navier-Stokes equations together with a k-6 turbulence model has been carried out for a two-dimensional internal ventilation flow. The study shows that for large ventilation areas, with associated velocity gradients, the assignment of turbulence parameters has a substantial effect on the solution.
