Aerodynamic/Atmospheric Boundary Layer Tunnel

The AABL is a closed-circuit wind tunnel with two test sections include aerodynamics test section and atmospheric test section. The Aerodynamics test section is 8 feet wide and 6 feet high, and the wind speeds varies from 23 mph to 110 mph. The atmospheric boundary layer test section is 8 feet wide and 7.25 feet high with length of 65 feet. In addition, a gust generator works independent of fan speed and can almost instantly increase mean wind speeds by 25 percent. The wind tunnel can be switched between closed- and open-circuit through controlling the door open or not at the first and second corners. The capabilities of AABL include PIV, pressure, and force measurement.
