Airflow Sciences designs and fabricates custom wind tunnels for aerodynamic testing. Test section size can range from small (6"x6") to quite large (4'x8') depending on your needs. We can design the tunnel and provide drawings for you or your contractor to build, or we can manufacture and provide a turn-key system with fan control, data logging, force balance, and other instrumentation. Standard subsonic wind tunnels are a breeze for Airflow Sciences, or custom tunnels with environmental control (temperature, humidity) or even rain/fog simulation are also up our alley.
Past Projects
Wind tunnel with 3' x 3' test section, 75 MPH velocity range, with water droplet injection for rain/fog simulation.
Closed circuit wind tunnel in the initial design phase.
Wind tunnel with 17" x 34" test section, 190 ft/s (130 MPH) velocity range, originally used for golf ball aerodynamic design and golf club drag analysis. Also compliant with US EPA test protocols (Method 2, 2F, 2G) for velocity probe calibration. Learn more about our in-house wind tunnel in a recent YouTube video.
Wind tunnel with 4'x8' test section for environmental flow testing around a scale model of buildings (1/100 scale) in a portion of downtown Detroit, Michigan. The tunnel includes a 360-degree turntable to allow any incoming wind direction to be analyzed, along with appropriate spires and surface roughness generators (the "fetch"), to represent the Earth boundary layer for wind approaching the buildings.
ASC builds a variety of small wind tunnels for aerodynamic experiments and flow testing. Tunnels can include force balance, turntable, pressure taps, particulate injection, gas injection, or other physical elements depending on the test needs. Test sections can be horizontal, as shown in left image, or vertical, as shown in right image. This tunnel has high temperature capability (550 F), is insulated with pyrex viewing windows, and includes particulate injection to evaluate erosion and pluggage of screens, filters, and other products installed in the test section.
