Rapid compression machines (RCMs) are widely used to acquire experimental insights into
fuel autoignition and pollutant formation chemistry, especially at conditions relevant to …

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 presents recent progress in the field of thermoacoustic combustion instabilities in
propulsion engines such as rockets or gas turbines. Combustion instabilities have been …

Self-excited thermoacoustic instabilities as frequently observed in rocket motors, gas
turbines, ramjets, and aeroengine afterburners are highly detrimental and undesirable for …

In this work, we develop a 2D numerical model of a Y-shaped bifurcating combustor with a
Helmholtz resonator attached. Propane (C 3 H 8) is fueled and burnt with air by applying …

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 …

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 …

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 …
