Acoustics in the Klebanoff-Saric Wind Tunnel: Background Identification, Forcing, and Active Control (2012-07-16)Low disturbance wind tunnels, such as the Klebanoff–Saric Wind Tunnel (KSWT), offer an ideal environment to study boundary layer transition. In particular, the leading-edge receptivity of sound can be measured by creating ...
-
(2016-11-18)During low speed maneuvers, such as landing and approach, a significant portion of the noise generated by transport aircraft is due to airframe noise. The leading-edge slat is a primary source of airframe noise. Previous ...

(2019-07-11)The Texas A&M Oran W. Nicks Low Speed Wind Tunnel (LSWT) uses a large pyramidal-type external force balance to measure aerodynamic loads. This balance was designed and constructed in the 1940s and measures the six wind ...
-
(2020-04-15)This thesis presents designs and implementations of 2-D Particle Image Velocimetry (PIV), stereo-PIV, and selective seeding that enable application of PIV in large-scale, production-type wind tunnels. The PIV systems use ...
-
(2017-12-04)Sting-mounted models that undergo significant unsteady motion suffer from degraded data quality because the data is time-averaged to remove the unsteady fluctuations. However, time-averaged data is not always an accurate ...

Evaluation of PM10 and Total Suspended Particulate Sampler Performance Through Wind Tunnel Testing (2011-10-21)Particulate matter (PM) concentrations in ambient air can be monitored by gravimetric sampling near a source using Federal Reference Method (FRM) samplers. PM is regulated by size, with PM10, which is comprised of particles ...
-
(2020-06-11)Aircraft noise is a source of disruption and annoyance to those living within close proximity to airports. Airframe noise is a main contributor to the overall noise level created by aircraft during approach and landing. ...

(2021-04-06)Successful wind tunnel testing requires careful attention to how model mounts may affect data quality. In several past sting-mounted tests at the Oran W. Nicks Low-Speed Wind Tunnel (LSWT), the High-Attitude Robotic Sting ...
