Abstract
This paper focuses on the localisation of noise sources in transonic cavity flows. Beamforming is used to estimate the pressure fluctuations inside a resonant transonic cavity, showing the localisation of the main sources of noise using an acoustic array and also combining it with a mean flow-field. The influence of the microphone array position, density, and shape is investigated. The presented method models the noise propagation with simple assumptions that are easily applicable to wind tunnel testing and may help localise the noise sources from complex geometries without intrusive methods.
