Whistling of turbulent cavity flows: Self-consistent predictions with the linearized compressible Navier-Stokes equations
Nikolaos Bozikis, Dilara Ãzev, Nicolas Noiray
A self-consistent saturation model for the prediction of aeroacoustic limit cycles emerging in turbulent low-Mach cavity flows (Re=O(10^5), M\simeq 0.2) is proposed. It predicts th…

A real-time digital twin of azimuthal thermoacoustic instabilities
Andrea Nóvoa, Nicolas Noiray, James R. Dawson +1
When they occur, azimuthal thermoacoustic oscillations can detrimentally affect the safe operation of gas turbines and aeroengines. We develop a real-time digital twin of azimuthal…
