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 …

Since its birth in the 1920s, quantum mechanics has motivated and advanced the analysis of
linear operators. In this effort, it significantly contributed to the development of sophisticated …

In this paper, we apply the novel EPTD (Exceptional Point-based Thermoacoustic Design)-
method derived in part I of this study (M. Casel & A. Ghani, Combust. Flame, 2024) to two lab …

In this conceptual study, we introduce the novel EPTD (Exceptional Point-based
Thermoacoustic Design)-method for the design of stable thermoacoustic systems: dampen …

We present a two-step optimization (TSO) framework, which uses the pressure data of an
unstable combustion process to estimate the complex-valued flame transfer function (FTF) …

We investigate the thermoacoustic response of a simple laboratory combustor where the
flame response is varied systematically by combining hydrogen enrichment with coherent …

Spectral degeneracies where eigenvalues and eigenvectors simultaneously coalesce, also
known as exceptional points, are a natural consequence of the strong non-normality of the …

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 …
