The U.C. Berkeley/FML low-turbulence subsonic wind tunnel is one of the largest low-turbulence wind tunnels in existance. The tunnel has a 80cm x 80cm x 3m test section and measured turbulence levels are less than 0.5%. The tunnel has a computer controlled feedback loop to keep desired wind velocities stable. A schematic of the tunnel is shown below.

Wind Tunnel Schematic

The wind tunnel has a six-component sting balance, a two-dimensional traverse with probe mounts, and a computer station to control and measure wind velocity, probes, and model parameters. The tunnel is used for both research and instruction and is available for industrial research needs.
