Thermoacoustic instabilities arise from the feedback between an acoustic field and the unsteady heat released in a burner, yielding self-sustained oscillations. A fundamental framework for modeling thermoacoustic instabilities in systems where a mean...

Green’s function analysis of nonlinear thermoacoustic effects under the influence of noise in a combustion chamber (2024)
Journal Article
Arabi, S., & Heckl, M. (2025). Green’s function analysis of nonlinear thermoacoustic effects under the influence of noise in a combustion chamber. Journal of Sound and Vibration, 594, Article 118621. https://doi.org/10.1016/j.jsv.2024.118621

This paper presents an analytical study to predict the effect of noise in a thermoacoustic system. The starting point of our analysis is the acoustic analogy equation with two source terms: one represents the fluctuating heat release rate, and the ot...
