An Effel-type boundary layer wind tunnel has been installed at Dept. of Arch., University of Tokyo to examine flows in the wind tunnel and also to propose basic specifications of wind tunnels for both environmental and structural engineering purposes. The working section of the wind tunnel is 0.7m in height, 1.0m in width, and 4.2m in length. The range of wind speed is from 0.5 to 15.0m/s and the uniformity of mean wind speed and the intensity of turbulence are within ± 1.8%, 1.5%, respectively. Characteristics of the boundary layer flow made by spires and roughness blocks in the wind tunnel are also presented in this paper.
