[PhD] Experimental identification of aeroacoustic sources in a wind-tunnel by using a three-dimensional microphone array.

PhD position
36 months

This experimental project aims to develop a new methodology for investigating aeroacoustic noise sources in a wind-tunnel, based on a latest generation of microphone antenna made up of 1024 MEMS sensors forming a tunnel around the flow of the wind-tunnel. Signal processing strategies based on three-dimensional beamforming or on the time-reversal technique have been developed in recent years. The aim of the PhD is to continue the development of these techniques to make them fully operational for their application to realistic cases that can potentially combine the following characteristics, for which current techniques are not operational: a turbulent flow causing sources of unsteady noise, strongly three-dimensional obstacles, significant diffraction effects from the installation or obstacles. An important part of the work will then be devoted to the development of signal processing tools and to their application to challenging experimental cases. More details can be found in the attachment.
