CSU-WT1 wind tunnel
The CSU-WT1 wind tunnel was completed and officially put into use in 2012. The wind tunnel is a closed-circuit low-speed wind tunnel with a fully steel structure. The main circuit of the wind tunnel consists of two experimental sections, one power section, two stable sections, two contraction sections, three diffusion sections, and six corner sections. The power section is composed of six 335KW DC motor driven axial fans arranged in parallel to form an array fan section. There are two test sections in the CSU-WT1, with a low-speed test section of 12 m wide, 3.5 m high, and 18 m long, with a wind speed range of 0-20 m/s and turbulence intensity less than 1%; The high-speed test section is 3 m wide, 3 meters high, and 15 m long, with a wind speed range of 0-94 m/s and turbulence intensity less than 0.5%. The CSU-WT1 is equipped with advanced instruments and equipment such as high-frequency electronic pressure scanner, high-frequency wind tunnel balance, cobra probe, hot wire anemometer, laser displacement sensor, three component force sensor, micro pressure sensor, acceleration sensor, dynamic data acquisition and analysis system, which is suitable for carrying out aerodynamic research on bridge wind engineering, train aerodynamics, structural wind engineering, wind environment, wind energy utilization, etc.
CSU-WT2 wind tunnel
The CSU-WT2 wind tunnel was completed in 2022 and is a closed-circuit wind tunnel. The experimental section is 1.5m long, 0.8m wide, and 1.2m high, with continuously adjustable wind speeds in the range of 2-30m/s, and turbulence intensity less than 1%.
