The experiments are conducted in the state-of-the-art aeroacoustic wind tunnel facility at Bristol, using highly instrumented NACA-series aerofoils, including NACA 0012, NACA 65-410 and NACA 16-series aerofoils.  With a full range of near-field pressure and velocity, and far-field noise measurements, the study aims to shed new light on aerofoil aerodynamic noise generation mechanism under different separation and stall mechanisms. Moreover, it presents an experimental campaign on aerofoil noise to produce richer and more comprehensive near- and far-field data sets, to be disseminated publicly. This project cuts across multiple areas and it aims to promote a range of high-quality academic and industrial research.
