Wind Tunnels Lab

Directed by: Dr. Colin Britcher & Dr. Drew Landman

The Wind Tunnel Laboratory houses three different wind tunnels. The most commonly used one being the Closed-Circuit Low-Speed Wind Tunnel. There is also an Open-Circuit Low-Speed Tunnel with 6" Test Section. Finally, the laboratory houses a Supersonic Wind Tunnel. This page concentrates on the Closed-Circuit Low-Speed Wind Tunnel.
