Flow Quality Measurements in the Klebanoff-Saric Wind Tunnel

Abstract

The Klebanoff-Saric Wind Tunnel is a low-speed, closed-return facility with lowdisturbance flow capabilities suitable for boundary-layer stability and transition studies. Previously known as the Arizona State University (ASU) Transition Facility or the ASU Unsteady Wind Tunnel, the tunnel was relocated to Texas A&M University in 2005. During its subsequent reconstruction, several component modifications were introduced, including more advanced acoustic treatments, pneumatic isolation, duct reshaping, and motor-drive alterations, to further enhance flow quality and experimental control. Details regarding the tunnel capabilities, flow quality improvements and tunnel calibration are provided. Freestream turbulence and acoustic measurements are given.
