Abstract

In this paper, we are interested in the impact of shape of obstacle roof on the turbulent flow in a wind tunnel. Particularly,arched, inclined, pitched and flat roofs obstacles are examined. A three-dimensional flow of a fluid is numerically analyzed using the Navier-Stokes equations in conjunction with the standard k-ε turbulence model. These equations were solved by a finite-volume discretization method. The comparison between our numerical and experimental results shows a good agreement and confirms the numerical method.
