Technology Transfer
Wind Tunnel for the Study
of Industrial and Urban Sites
Applications
Lille Site in the L2 site wind-tunnel
Aluminium production plant in L2
> Civil Engineering
- Building layouts and interaction study.
- Wind effect on structures (cranes, bridges, statues, flags, etc.) and free or forced ventilation inside buildings.
- Pedestrian comfort and wind protection systems.
- Chimney exhaust systems.
> Environment
- Climatic analysis.
- Pollution and dust dissemination.
Keywords
- Wind tunnel, town planning, pollution impact
Advantages
- Wind tunnel well adapted for the study of complete urban and industrial sites with simulations of wind flow boundary layers.
- Internal and external impact on site considered.
Testing
- A 6m turn table is used to guide the model into the fans.
- Variable wind speed up to 20m/s.
- Model dimensions possible: 9 x 6 m with 2.5m height.
- Measurements of Forces and Moments, Pressure, Speed, Temperatures.
- Visualisation of flow by laser tomoscopy.
- A system of 3 axe displacement is controlled by the computer to ensure the continual positioning of the probes.
Customers
- Aluminium Dunkerque, Cetim, Elf, Euralille, Fives Cail Babcock, Fonderies du Poitou, Michelin, SNCF
