Abstract

The present paper is dedicated to the numerical simulation of the height effect of an inclined roof obstacle. The governing equations of mass and momentum in conjunction with the standard k-ε turbulence model are solved using the computational fluid Dynamics (CFD). The numerical method used a finite volume discretization. Experiments in wind tunnel are also developed to measure the average velocity near two inclined roof obstacles. The numerical simulations agreed reasonably with the experimental results and the numerical model was validated.
