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 …

The unsteady response of a flame to acoustic or flow perturbations plays a crucial role in
thermoacoustic combustion instability. The majority of studies on this subject presents and …

This article describes recent progress on premixed flame dynamics interacting with acoustic
waves. Expressions are derived to determine the stability of combustors with respect to …

In a thermoacoustic system, such as a flame in a combustor, heat release oscillations couple
with acoustic pressure oscillations. If the heat release is sufficiently in phase with the …

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 …

We propose a general classification of all the modes of a given thermoacoustic system into
two sets: one of acoustic origin and one of intrinsic thermoacoustic (ITA) origin. To do this …

The present work compares the respective advantages and disadvantages of compressible
and incompressible computational fluid dynamics (CFD) formulations when used for the …

This conceptual numerical study explores a possible strategy for control of unstable intrinsic
thermoacoustic (ITA) modes. Control of the ITA feedback loop has not been discussed yet …

Abstract Large-Eddy Simulation (LES) is combined with advanced System Identification (SI)
to simultaneously infer models for the source of combustion noise and the dynamic …

Spectral distributions of the sound pressure level (SPL) observed in a premixed, swirl
stabilized combustion test rig are scrutinized. Spectral peaks in the SPL for stable as well as …
