Besides measurement of reference flow parameters (i.e reference wind speed, flow temperature, hygrometry, atmospheric pressure), different types of measurement method can be employed in this wind tunnel:

  • 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).
The SPIV system quasi-systematically employed in this wind tunnel provides measurements of the three-component velocity in a plane (typically more than 16 000 instantaneous velocity vectors), therefore allowing for the detailed investigation of turbulent flows within and above dense canopies.
