Environmental Wind Tunnel Laboratory

The wind tunnel serves as a bridge between meteorological field campaigns and numerical modelling in the lower atm​ospheric boundary layer.

The laboratory is a unique facility that provides a well-controlled platform for a variety of studies, such as:

- Study of turbulent transport and dispersion phenomena and model validation in downscaling mode of:

  • Atmospheric boundary layer flow and source releases.

  • Flow, transport, dispersion and turbulence in complex terrain and in urban environments.

  • Assessment of numerical models and support of field measurements.

Calibration and validation of meteorological instrumentation and sensors.

- Investigating engineering optimization problems.

- Wind tunnel specifications: ​

  • 32m long (13 m test section), with a 2m cross-section that produces flow velocities between 0.5-10 m/s.

  • Controlled ambient conditions in the range of 5-45°C and 20-80% humidity.

​State-of-the-art​ measurement instrumentation include ​a Particle Image Velocimeter (PIV) and a Laser Doppler Anemometer (LDA) mounted on a​ 3D automated traverse system.
