For the purpose of the experimental investigation of turbulent boundary layers, the boundary layer wind tunnel which is of some size for the one, was projected to make at the Hydraulic Laboratory in Yamaguchi University. From the detailed measurement of mean velocity and wall shear stress, careful consideration was given about two-dimensionality of flow fields and boundary layer development. The followings were revealed. 1) Setting up the reformed honeycombs, the flow fields become nearly two-dimensional in the range of z=±300mm. 2) In the case of natural transition, the boundary layer is equilibrium in the region lower than x≒600mm. From the results mentioned above, it may be right to consider that this wind tunnel has a thorough accuracy and an extensive usefulness for experimental researches for boundary layers.
