Analytical approximations for heat release rate laws in the time-and frequency-domains

SM Gopinathan, A Bigongiari… - International Journal of …, 2020 - journals.sagepub.com
This paper focusses on the relationship between the heat release rate and the acoustic field,
which is a crucial element in modelling thermoacoustic instabilities. The aim of the paper is …

Modeling the Influence of Gas Expansion on the Linear Response of Laminar Premixed Flames

A Zimmermann - 2018 - mediatum.ub.tum.de
Thermoacoustic oscillations, arising due to the interaction of the flame front and the
acoustics of the system, can reduce the life span of combustion systems. To counteract any …

Simulation of Self Sustained Thermoacoustic Oscillations by Coupling of a Low-Order Acoustic Network Model with a Level-Set Solver

M Brandl - 2016 - mediatum.ub.tum.de
Thermoacoustic oscillations can happen in nearly every device which includes a
combustion process. The reason therefore is that the combustion and the acoustics of the …
