About DNW

DNW is a non-profit foundation under Dutch law, with headquarters in Marknesse in the Netherlands. Its tunnels are situated in a number of locations in the Netherlands and Germany: Marknesse, Amsterdam, Braunschweig, and Göttingen.

General

DNW’s six wind tunnels include subsonic, transonic and supersonic facilities, and provide experimental aerodynamic simulation capabilities to the user community at large. This includes all aspects of airflow encountered in nature and engineering.

Simulation techniques

Full models

Full models are extremely suitable for testing an object’s stability and control, drag, aeroelasticity and acoustics. Test objects comprise all types of aircraft, vessels, trains and trucks, buildings and building components. 

Half models/ground vehicles

Half models enable a more detailed model representation than full models because larger scales can be used. Moreover, testing can be performed at higher Reynolds numbers. These conditions are favorable for wing design studies aimed at investigating Reynolds number effects or the influence of design changes, but also for studies on power plant installation effects of control surface effectiveness.
