Abstract The influence of Intrinsic Thermoacoustic (ITA) feedback on the combustion noise
spectrum produced by a confined, turbulent, premixed, swirl flame is investigated. The …

Combustion noise in gas turbine engines has recently become a relevant source of noise in
the aircraft due to the appearance of new burner architectures that are intrinsically more …

The combustion noise produced by a confined, turbulent, premixed swirl burner is predicted
with large-eddy simulation of compressible, reacting flow. Characteristics-based state-space …

This paper presents a numerical study of the sound generated by turbulent, premixed
flames. Direct numerical simulations (DNS) of two round jet flames with equivalence ratios of …

Combustion instability is a common phenomenon in solid rocket motors. Coupling between
pressure and heat release rate produces pressure oscillation, which seriously affects the …

Adverse effects of global warming due to the greenhouse gas emissions is changing the
actual paradigm for the use energy resources. In the absence of a mid-term solution for …

The objective of this study is to evaluate the effects of numerical and model setups on the
large-eddy simulation (LES) predictive capability for the internal flow of a propulsion …

Thermoacoustic Helmholtz solvers provide a cheap and efficient way of predicting
combustion instabilities. However, because they rely on the inviscid Euler equations at zero …

Abstract The Large Eddy Simulation/System Identification (LES/SI) approach allows to
deduce a flame transfer function (FTF) from LES of turbulent reacting flow: Time series of …

Three asymptotic limits exist for the Euler equations at low Mach number-purely convective,
purely acoustic, and mixed convective-acoustic. Standard collocated density-based …
