USA Wind Tunnels
SOH Wind Engineering has two large wind tunnels in Williston, Vermont, USA. Williston is located 5 miles from the city of Burlington.
The Williston wind tunnels have a closed return flow and consist of 2 parallel tunnels. Each wind tunnel is fully operational on its own as it is forming a closed circuit with its own fan and separate return flow. The test section of each wind tunnel is 3 x 3 m. Optionally the two tunnels can be combined creating an even larger test section of up to 6 x 3 m (w x h).
The wind was turned on for the first time in two of the four wind tunnels in September 2012. In January 2013 Vermont´s local TV-station visited the Williston Wind Tunnels. See the two minutes news clip from the wind tunnels here and read the press impressions from the grand opening in March 2013: Williston Observer, VTDigger, Burlington Free Press.
The calibration procedure and quality assurance has led to an accreditation by ANAB declaring that SOH Wind Engineering now performs the calibrations of anemometers in a way that fulfil the international standard ISO 17025. SOH Wind Engineering is also a member of MEASNET.
