UKAN+ Webinar: The Third Golden Age of Aeroacoustics

The Aeroacoustics SIG is pleased to welcome Stéphane Moreau to present a webinar: The Third Golden Age of Aeroacoustics. The webinar will be held over Zoom and the joining link will be sent to you 1 hour before the start time.

Synopsis:

The presentation will cover the latest evolution of computational aeroacoustics, the field that deals with the noise generated by fluid flows and its propagation in the medium. It will highlight the latest findings in both free flows (jet noise) and wall-bounded flows (airfoil, airframe, and turbomachinery noise) in more and more complex environments. Among the computational aero-acoustics methods, high-order schemes of the Navier–Stokes equations on unstructured grids and the lattice Boltzmann method on Cartesian grids have emerged as excellent candidates to tackle noise problems in realistic complex geometries. The latter is also shown to be particularly efficient for both noise generation
and propagation, allowing to directly estimate the noise in the far field. Several examples of application of such methods will be presented ranging from complex jet noise and to installed airfoil noise and turbomachinery noise.

About the speaker:

Stéphane Moreau obtained his engineering degree and MSc from ISAE- Sup’Aéro (France) in 1988. He then got his PhD in Mechanical Engineering with a minor in Aeronautics and Astronautics from Stanford University in 1993. He then worked for a start-up company AC2 on plasma physics in 1994 where he developed the plasma micro-thruster concept used nowadays on most satellites. He then worked for a year at the turbo-engine builder Snecma (now Safran Aircraft Engines) on nozzle designs. Late 1995 he joined the automotive Tier-1 supplier Valeo where he worked for 13 years on engine cooling fan system design and promoted simulation in all branches of the company. He then joined the Mechanical Engineering faculty of Université de Sherbrooke in 2009 as an associate Professor. He became a full professor in 2011. His research topics include aeroacoustics, turbomachinery design, turbulence and CFD (Computational Fluid Dynamics). He has more than 670 scientific publications with more than two third in aeroacoustics with significant contributions in analytical noise modeling, experimental noise measurements and large scale numerical aeroacoustic simulations noticeably for turbomachinery applications (requiring high power computing for instance).
