Numerical Simulation of Non-normal Wind Load on Porous Fences

This paper presents a numerical simulation of non-normal wind loads on a porous fence. It was found that non-normal wind load has significant impact on the performance of the fence in terms. The performance of the fence was measured as the effective fence zone behind the fence where flow characteristics and normal drag coefficients were maintained within safe level. It is recommended the incidental angle between the most prevalent wind direction and the fence position is preferably less than 15° but and no more than 30°.
