We will start the talk with a presentation of the large eddy simulation approach based on relaxation filtering (LES-RF). This method represents a return-to-first-principles in turbulence simulation, in that the artificial-viscosity paradigm, used by most turbulence models of the past half-century, is replaced by an explicit relaxation filtering. Aeroacoustics is today a central element in many engineering areas as aeronautics, ground transportations or energy production.We will summarized recent work regarding the direct computation of aerodynamic noise, and the use of these simulations to improve our understanding of noise generation by turbulent flows.
