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 …

Computational prediction of thermoacoustic instabilities arising in gas turbine and aero-
engine combustors still remains a challenge especially if fuel is injected in a liquid spray …

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 …

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) …

Acoustic liner is generally adopted to damp noise in aero-engines and gas turbines. This
paper presents a systematic study about the effects of an acoustic liner on thermoacoustic …

In the present work, the combustion instability of a premixed swirl combustor was
experimentally and theoretically investigated. Results show that both intrinsic …

The intrinsic thermoacoustic (ITA) feedbackloop constitutes a coupling between flow, flame
and acoustics that does not involve the natural acoustic modes of the system. One recent …

Thermoacoustic instabilities originate from the interaction of unsteady heat release rate
associated with flames and the acoustic modes of a combustor. A feedback loop not …
