We examined how to generate the boundary layer, roughness length close to the natural field, uniform distribution of wind speed in the horizontal direction, and stable observation field of a simple wind tunnel. Without rearranging the roughness block, we proposed to adjust only the shape and number of speyer. As a result, the boundary layer became 36 cm and roughness length became 0.01 cm, which was close to the natural condition. Additionally, it was possible to develop a uniform wind speed in the horizontal direction, and a stable observation field of the wind speed distribution.
