Subsonic Wind Tunnel: Design & Build

Wind tunnels are measurement tools to study gas flows around a body and the forces generated by the gas-body interaction. For the most part, air is used in wind tunnels.

Using such tool it is possible to measure global and local flow velocities, as well as pressure and temperature around the body. Moreover, optical tests using special insemination substances or wool wires can be performed to visualize flow motion.

Technical data: test section 500 x 500 x 1130 mm; max wind speed with open test section:
30 m/s; turbulence level: 0.4%.
