Abstract

In establishing artificial fences in a certain locality, type of its area or wind blown against them from the front side is primarily considered. Researchers on fences also concentrate on upstream, wand blown against them from the front side In 90$^{\circ}$ angle. In this research, simulations were carried out on the direction of wind changed by each season, and regardless of seasonal wind, on the fences effect of wind direction on fences, throu호 an atmospheric boondary layer wind tunnel. When I compared the velocity distribution of upstream against the fences in 90$^{\circ}$ angle with that of 75$^{\circ}$, 60$^{\circ}$, and 45$^{\circ}$ respectively, the velocity distribution at downstream of the latter cases generally surpassed that of the former one.
