Arizona Low-Speed Wind Tunnel
Also affiliated with the Turbulence and Flow Control Laboratory
ALSWT was installed in 2013 with funding from AFOSR and the University of Arizona. It is a closed return, low-turbulence that supports multiple PIs in fields such as transition, flow control, turbulence, wind energy, and more.
