The UNSW Acoustic Tunnel is a low-noise open jet anechoic wind tunnel facility used in the study of flow-induced noise and aeroacoustic phenomena.
Major specifications:
- Open jet test section of size 0.45 m x 0.45 m
- Operating flow velocity of 5 to 60 m/s
- Turbulence intensity of 0.67% at 20 m/s
- Anechoic chamber of size 3 m × 3.2 m × 2.15 m
- Anechoic chamber walls are acoustically treated with 0.25 m thick Melamine foam, creating a semi-anechoic environment above 300 Hz
- Supports point microphone measurements, acoustic beamforming, near field acoustic holography, hot-wire anemometry, mean and unsteady pressure measurements, Particle Image Velocimetry (PIV) and aerodynamic force measurements
