Nicolas Noiray

Prof. Dr. Nicolas Noiray is a professor in the Department of Mechanical Engineering at ETH Zurich. His research focuses on combustion technology and the control of hydrodynamic, thermoacoustic, and aeroacoustic instabilities. He also develops flow sensors and actuators. His work addresses challenges in managing complex fluid dynamics and acoustic phenomena in combustion systems.

Nicolas Noiray's research focuses on combustion instabilities, flame dynamics, and thermoacoustic oscillations in gas turbine combustion chambers. His work explores nonlinear flame transfer functions, azimuthal staging concepts, and the dynamic nature of thermoacoustic modes. He investigates deterministic quantities characterizing noise-driven Hopf bifurcations and develops methods to identify thermoacoustic growth rates from dynamic pressure data. Noiray also examines passive control strategies for combustion instabilities, such as using perforated plates and novel damping devices. His studies integrate experimental analysis, theoretical models, and computational simulations to address challenges in combustion noise and instability mitigation.
