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 paper investigates the simplifying assumptions used for deriving low order models of
thermoacoustic instabilities and thermoacoustic intermittency in turbulent combustor. These …

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

A methodology is developed where the acoustic response of a swirl stabilized flame is
obtained from a reduced set of simulations. Building upon previous analytical flame transfer …

Abstract We investigate the Flame Transfer Function (FTF) of a lean-premixed, laminar slit
flame numerically. Based on the reference case at atmospheric pressure, we investigate four …

The acoustic energy balance of a sudden area expansion is known to be altered in the
presence of a mean flow. In this work, Ronneberger's quasi-steady model describing the …

Acoustic transfer matrices are widely used in the analysis of combustion dynamics of gas
turbines. The reliability of the analysis thus depends on the quality of the determination of …

In a context where the aviation sector is actively looking into replacing standard jet fuels with
sustainable aviation fuels (SAFs), examining the effects of fuel composition on combustion …

The stringent emission requirements for the next generation of aero-engines have increased
interest in combustion chamber designs that employ lean-burn combustion technologies …

Predicting the occurrence of thermoacoustic instabilities is of major interest in a variety of
engineering applications such as aircraft propulsion, power generation, and industrial …
