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.
