CSU-1 Wind Tunnel: A close-circuit atmospheric boundary layer wind tunnel with two test sections.

CSU-1 wind tunnel belongs to the National Engineering Laboratory for High-speed Railway Construction, which has six major experimental systems.

CSU-1 wind tunnel had been constructed since 2009 to 2012, which is a Close-circuit atmospheric boundary layer wind tunnel with two test sections. The low speed section is of 12 m wide, 3.5 m high and 18 m long. The wind speed in the low speed section ranges from 0-20 m/s, with a turbulence intensity of 1%. The high speed section is of 3 m wide, 3 m high and 15 m long, with wind speed ranges from 0-94 m/s, and turbulence intensity less than 0.5%.
