The Atmospheric Boundary Layer (ABL) wind tunnel is located at the University of Minnesota's St. Anthony Falls Laboratory. Designed for modeling of the air/land boundary layer, the tunnel can operate with recirculating or once-through flow. It can reach speeds of up to 148 ft/s (45 m/s), and is equipped with a glass observation wall, rotating turntable, smoke generator, and laser instrumentation system. Capable of reproducing natural wind conditions, including temperature and surface variations, the ABL wind tunnel is uniquely suited to wind energy research.
