The special low- speed wind tunnel at the Environmental Mechanics laboratory allows scientists to undertake fundamental studies on how air interacts with the earth's surface. At this 'boundary layer', both smooth and turbulent flows are possible. The wind tunnel is driven by a powerful double-inlet centrifugal fan.
Air is blown down the test section, enters the ambient space, and is then recycled.
The working section is 1.8 m wide, 0.9 m high, and 16 m long. The tunnel was built in 1967, and a major addition in 1994 was a traverse gear and probe system.
