The purpose of the chimney is to diffuse the exhaust gas discharged from power plants and factories over the sky and to reduce the concentration of exhaust gas reaching the ground. Since the diameter and height of the chimney are determined so that the exhaust gas concentration satisfy the environmental standards, it is not unusual the case that the aspect ratio becomes 20 or more. In this research, in order to clarify the aerodynamic properties working on a cylindrical shape with a large aspect ratio, wind tunnel experiments were carried out, mainly focusing on wind pressure distribution.
