摘要

This paper will describe the anechoic wind tunnel facility located at the University of New South Wales (UNSW) Sydney. The wind tunnel construction, including the inlet contraction and fan system, will be described along with the design of the anechoic chamber and muffler system. The model mounting system is located in an open jet, with integrated force measurement system via a turntable mount. Aeroacoustic measurements are performed with an aeroacoustic microphone array, whose design, construction and signal processing will be explained. Aerodynamic measurements using hot-wire, pitot and PIV systems are used and integrated with acoustic measurements. A remote microphone measurement system has been used with a novel calibration methodology to measure the turbulent wall pressure spectra in a variety of configurations. In addition to an extensive description of the construction and performance of the wind tunnel, selected results from recent airfoil self-noise experiments will be included to demonstrate the acoustic measurement performance of the facility.
