Recent Advances in Aeroacoustics

Topic Information

Dear Colleagues,

Industries across all sectors share a common need for innovative technologies offering both higher performance and lower emissions. Although chemical emissions are of primary importance, acoustic ones have become just as critical. Among the numerous sources of environmental noise, those of aerodynamic origin plague various industry sectors, e.g., transport (aircraft noise, railway noise, road traffic noise), energy (wind turbine noise), civil engineering (HVAC noise), and so on. Mitigating aeroacoustic emissions, however, is a daunting task since part of the flow-noise physics still eludes us. Indeed, whereas classical (linear) acoustics has been mastered over the last two centuries, aeroacoustics still raises a lot of challenges, whether from a theoretical, computational, or experimental viewpoint. This especially concerns those aspects that involve some interplay between aerodynamic and acoustic phenomena, whether they relate to noise generation by unsteady flows or its alteration by flow-induced mechanisms (e.g., refraction induced by flow gradients, diffusion incurred by small-scale turbulence, attenuation entailed by viscous dissipation, exacerbation driven by flow instabilities). Although many pioneering, background works have helped to partly unveil some of these flow–noise interactions, more still has to be achieved for them to be fully understood from a fundamental viewpoint and mastered from a practical perspective.

This Topic seeks to collect and disseminate recent, significant contributions to the fascinating, albeit challenging, research domain of aeroacoustics. All types of works (theoretical, computational, experimental) are welcome, whether of fundamental or applied nature. Those which fall into the category of flow–noise interplay are especially sought after. We look forward to receiving your contributions, whether original research articles or reviews.
