The wind tunnel serves as a bridge between meteorological field campaigns and numerical modelling in the lower atmospheric 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.
