Acoustic resonances in open systems, which are usually associated with resonant modes
characterized by complex eigenfrequencies, play a fundamental role in manipulating …

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 …

Open-loop control of self-excited flame pulsating oscillations and thermo-acoustic instability
is considered in this work. The performance of the control strategy is numerically evaluated …

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 …

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

In this paper the nonlinear dynamics of the pure Intrinsic Thermo-Acoustic (ITA) modes are
experimentally investigated for burner stabilized premixed flames by decoupling them from …

Acoustic dampers are efficient and cost-effective means for suppressing thermoacoustic
instabilities in combustion chambers. However, their design and the choice of their purging …
