Atmospheric Boundary Layer Wind Tunnel

Discover the Wind Tunnel at TU Eindhoven:
At TU Eindhoven, our state-of-the-art wind tunnel enables cutting-edge research into how air moves around objects—both still and in motion. Stretching 46 meters in total length, with a 27-meter test section that’s 3 meters wide and 2 meters high, this closed-circuit atmospheric boundary layer wind tunnel allows us to recreate winds from 0 to 30 meters per second under highly controlled conditions.

Recreating Atmospheric Flow:
The tunnel’s long test section enables us to replicate real-world wind conditions, including the atmospheric boundary layer that develops naturally over different types of terrain. By combining specially designed elements and vortex generators, we can simulate wind flows at a wide range of geometric scales - from 1/40 to 1/500 - matching conditions defined by international civil engineering standards.

What We Explore:
Our research helps answer real-world questions about airflow in urban and environmental contexts. Experiments are typically conducted using carefully scaled models, allowing us to transfer results obtained at model scale to real-word conditions. For example, we investigate:

• How wind affects comfort and safety for pedestrians in cities.
• How pollution and particulate matter spread through urban areas.
• Wind loads on large structures (e.g., ships, building complexes, stadiums).
• Natural ventilation potential in buildings.
• Wind energy applications, including wake effects behind turbines and their interactions.

The wind tunnel is equipped with state-of-the-art measurement equipment to support accurate and reliable experiments. A fully automated, three-degree-of-freedom traverse system for sensor positioning and a 2.6-meter automated turntable enables accurate rotation and orientation of equipment and models.

Lastly, the wind tunnel can also be used to study the aerodynamics of moving objects, such as vehicles, cyclists, or skaters. For larger objects, the first nine meters of the test section can be adapted by removing the ceiling and walls and installing a hydraulically operated platform. Two turbulence grids allow precise control of airflow, making it possible to investigate how different levels of turbulence affect the performance and behavior of the objects.

Impact of Our Research:
The insights gained in the wind tunnel help design safer, more comfortable, and sustainable urban environments. By understanding how wind interacts with buildings, streets, and infrastructure, our work supports improved city planning, pollution management, natural ventilation strategies, and renewable energy optimization. This research ultimately contributes to healthier, more efficient, and resilient communities.
