2 x 3-Foot Boundary Layer Tunnel

The 2 x 3-ft Boundary Layer Tunnel is a self-contained device capable of speeds up to approximately 100 miles per hour, and it incorporates a honeycomb, four screens, and a 10:1 contraction ratio to reduce turbulence. The floor and ceiling of the 20-foot-long test section are adjustable to allow operators to set a desired longitudinal pressure gradient. Additionally, the tunnel is equipped with acoustic drivers upstream and downstream of the test section to excite the flow as needed.
