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

• Buildings layout 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 orientate 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 axes 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
