Laminar Wind Tunnel

The Laminar Wind tunnel is used both for education and research purposes at the Fluid Dynamics Laboratory. It is equipped with a multi-channel manometer, vertical multi-pressure probe, NACA air foil with internal pressure piping on both surfaces, and a smoke generator.

Test station size: 25 x 40 cm
Flow velocity: 10-25 m/s
36-90 km/h
Contraction ratio: 16:1
Flow stability honey comb + 5 screens
Turbulence intensity clearly below 1%
