This open-circuit atmospheric wind tunnel has a 26-metre long test section and a cross-section of 2 m x 2 m, with transparent walls and floor and ceiling adjustable in height. Its centrifugal fan powered by a 45kW motor allows for maximum wind speed of 10 m/s. Its characteristics make it an exceptional means for the study of offshore boundary layer intercalations with fixed or floating wind turbines.
- 32-channel acquisition system equipped with 24 thermal anemometers dedicated to the use of single or multiple hot-wire probes,
- stereoscopic Particle Image Velocimetry (SPIV) system composed of a 200mJ Nd-YAG pulsed laser, two 4M pixels cameras with their dedicated synchronization, acquisition and post-processing unit,
- drag balance designed for the measurement of canopy element drag (< 0.5N),
- unsteady wall-pressure transducers (8 channels) and mean pressure transducers (96 channels).
