Wind tunnel Research Facilities with two test sections have been built for civil engineering structures and aviation applications. The test section for applications in civil engineering structures is a closed-type and has the dimension of 2.5m in height, 2.0m in width, and 15.Om in length. At the test section, wind velocities from 0.2m/s to 50m/s can be used. The wind velocity uniformity distribution is within ±0.6 %, turbulence intensities are less than 0.3 %, and static pressure distribution is less than 0.2 %/m. The test section for aviation applications is an open-type with the dimension of 2.5m × 2.5m × 5.0m. Wind velocities from 0.2m/s to 45m/s are available for this section and the uniformity of the wind velocity is within ± 1.0 %, and turbulence intensities are less than 0.3 %. The characteristics and performance of the Wind Tunnel Facilities are presented in this paper.
