The low-speed wind tunnel (DNW-NWB), operated by the foundation German- Dutch Wind Tunnels, is a versatile, closed-circuit wind tunnel for industry and research. It operates at atmospheric pressure and boasts high flow quality as well as excellent acoustic properties.
In combination with a powerful secondary air supply, it can be operated using an open, a ¾ open, a slotted or a closed test section. Different model support systems for static as well as dynamic tests are available.
- Test section size: 3.25 m × 2.80 m
- Free stream velocity: 90 m/s
- Fan power: 3.5 MW
- Auxiliary air supply: 1.6 MW
- Turbulence level: Tux = 0.05%
