Keynote Title:
The next age of turbomachinery noise predictions


In the last five years, significant progress has been achieved in the numerical prediction of the noise generated by low-speed and high-speed rotating machines. Such advancement has been possible by the emergence of two Computational Aero-Acoustics (CAA) technologies: high-order Navier-Stokes unstructured solver and the Lattice Boltzmann Method (LBM). After illustrating the capabilities of both approaches on the canonical airfoil noise, several examples will be shown for both low-speed and high-speed systems. This should bring some significant noise reduction in the upcoming propulsion systems such as the Ultra High Bypass Ratio engines.

Stéphane Moreau

Stéphane Moreau obtained his engineering degree and MSc from ISAE- Sup’Aéro (France) in 1988. He then got his Ph.D. 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. In 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, and CFD (Computational Fluid Dynamics). He has more than 550 scientific publications with more than two third of them 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).
