As a first step of low turbulence visualization wind tunnel production, it was produced a small and simple visualization wind tunnel. Basically, Visualization wind tunnel was made of acrylic. It was using a 12V DC fan for PC as a blower. The velocity distribution measurement, It was used a simplified hot-wire anemometer. The orijinal plastic honeycomb was used for straightening grid. As a result, the uniform flow is obtained in spite of simple structure. The average velocity measured by using HWA and it measured by using Karman voltex visualization were almost matched. In the future, it is planned to use this visualization wind tunnel at various scientific events.
