The influence of the injection system on combustion instabilities is investigated on a
laboratory-scale combustor equipped with a single injector that is weakly-transparent to …

Many gas turbine and rocket engines exhibit unwanted combustion instability at the
experimental testing phase. Instability leads to large amplitude pressure oscillations and …

This study assesses and compares two alternative approaches to determine the acoustic
scattering matrix of a premixed turbulent swirl combustor:(1) The acoustic scattering matrix …

Lean premixed combustion chambers fuelled by natural gas and used in modern gas
turbines for power generation are often affected by combustion instabilities generated by …

This paper presents a low-order thermoacoustic model for multi-burner combustors and
proposes a control theoretic approach to linear combustion instability analysis in frequency …

This study focuses on elucidating the flame dynamics of the lean burnout zone of an Rich-
Quench-Lean (RQL) combustion chamber. With a new experimental approach of spatially …

This paper presents a one-dimensional thermoacoustic model for a dump combustor in
terms of two acoustic impedances just before and after a flame/area-expansion location. A …

This paper presents a thermoacoustic model in the frequency domain for multi-burner
combustors composed of multiple plenum-nozzle-chamber modules with cross-talk at both …

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 …

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