Different Reynolds numbers equals to Re=2666, Re=10666, Re=24000 and Re=32000 are particularly considered. The software "SolidWorks Flow Simulation" has been used to present the local characteristics. The numerical model considered is based on the resolution of the Navier-Stokes equations in conjunction with the standard k-ε turbulence model. These equations were solved by a finite volume discretization method. The numerical model is validated with experimental results conducted on an open wind tunnel equipped by an adequate model. http://pubs.sciepub.com/rse/2/4/2/rse-2-4-2.pdf CFD modeling airflow obstacle inclined roof wind tunnel
