For most applications, turbulence is an unavoidable property of the flow around aerospace vehicles. Turbulence comprises a broad range of spatial scales ("eddies"), which are related to fluctuations of velocity and of thermodynamic properties within the flow. These fluctuations generate acoustic waves, which are capable of propagating to long distances with low attenuation; the consequence is that regions surrounding airports are constantly subjected to aircraft noise. Aeroacoustics is a branch of fluid mechanics devoted to the study of how turbulence generate sound. The understanding of the salient mechanisms of sound generation by turbulent flows is the basis for the proposition of solutions to make aircraft quieter.
