It is accepted that the thermoacoustic behavior of a given combustion system can be
analyzed by investigating how its natural acoustic modes are perturbed by the flame …

This paper utilizes Cauchy's argument principle in the frequency domain to develop novel
stability maps, providing guidelines for measures which can be taken to mitigate …

Nonlinear eigenvalue problems (NLEVPs) arise in thermoacoustics by considering the
temporal evolution of small perturbations in the relevant governing equations. In this work …

The Galerkin modal expansion is a well-known method used to develop reduced order
models for thermoacoustics. A known issue is the appearance of Gibbs-type oscillations on …

Power generation and aircraft gas turbine combustors are frequently operated under fuel
lean conditions to mitigate harmful emissions, rendering them susceptible to undesirable …

The thesis aims to improve the understanding of thermoacoustic system behavior by
employing and extending network model analysis. The proposed methods and …
