Abstract
<p>Atmospheric boundary layer flow impinging on a large cylindrical structure often reaches a supercritical Reynolds number. The flow in this region on the wind tunnel scale is difficult due to limitation of wind tunnel performance. Generally, in order to reproduce the drag coefficient of the transcritical Reynolds number region, a method of providing a roughness on the cylindrical surface is used. Many experiments have been reported for the flow around a cylinder with roughness, but few analysis examples using LES have been published. Therefore, in this paper, for the substitution by the numerical analysis of the experiment for the chimney, numerical analysis of the flow around the two - dimensional cylinder with roughness using LES, the aerodynamic coefficient was obtained and compared with the experimental result.</p>
