Benjamin Cotté

Benjamin Cotté is an Associate Professor at ENSTA Paris, a member of Institut Polytechnique de Paris, where he works in the Mechanics Unit (UME) within the Institute of Mechanical Sciences and Industrial Applications (IMSIA UMR 9219). His research focuses on fluid dynamics and acoustics, particularly in modeling and simulation of noise sources and their propagation in various environments.

His research interests include the modeling and simulation of aeroacoustic sources and their propagation in inhomogeneous environments, with applications to wind turbine and marine propeller noise, and sound synthesis using physical models of aero- and vibro-acoustic sources. Cotté has developed expertise in wind turbine noise modeling based on Amiet's theory, studying the effects of wind shear and atmospheric turbulence, as well as extended source models for wind turbine noise propagation that account for blade motion.

His recent publications reveal a strong focus on wind turbine noise propagation, aeroacoustics, and sound synthesis. His work combines theoretical modeling with experimental validation, particularly in dynamic stall noise characterization. Cotté's research spans both renewable energy applications (wind turbines) and musical acoustics (piano soundboards).

Scientific Awards and Funding:

• ANR PIBE project (Prédire l'Impact du Bruit des Eoliennes) for dynamic stall noise research
• ANR funding for the MAESSTRO project (Computer-aided design of piano soundboards)
• DGA funding for time-domain damping models in structural acoustics
• ITN VRACE project (Virtual Reality Audio for Cyber Environments) for wind turbine noise auralization

Collaborations: Cotté collaborates extensively with researchers from Ecole Centrale de Lyon (Michel Roger, Emmanuel Jondeau, Pascal Souchotte) and works with Antoine Chaigne and Roberto Viggiano on piano acoustics research.

Advising: Cotté has supervised multiple PhD students and postdocs including David Raus (2019-2021), Lisa Sicard (2020-...), Yuan Tian (2012-2016), and David Mascarenhas (2020-...), focusing on wind turbine noise, aeroacoustics, and sound synthesis.
