Particle Image Velocimetry in large-scale wind tunnels
Wind tunnels are important for aerodynamic measurements on wind tunnel models. The use of the largest wind tunnel of TU Delft in combination with the Particle Image Velocimetry technique provides much more detailed results with improved scalability to actual sized objects.
Aerospace engineering has a laboratory with 10 wind tunnels with maximum wind speeds from 120 km/h to 13000 km/h (<MACH 1 to MACH 11). Test section dimensions vary accordingly. The 3 x 3 m test section of the Open Jet Facility is the largest, enabling large scale test objects such as a cyclist.
