In many continuous combustion processes, such as those found in aeroengines or gas
turbines, the flame is stabilized by a swirling flow formed by aerodynamic swirlers. The …

Accurate prediction of limit cycle oscillations resulting from combustion instability has been a
long-standing challenge. The present work uses a coupled approach to predict the limit …

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 …

Limit cycles of combustion instabilities can be estimated by studying the nonlinear behavior
of flame dynamics. In the present study the flame describing function (FDF) framework is …

Features of the flame transfer function (FTF) are characterized for turbulent, non-swirled,
bluff body stabilized “M” flames for different hydrogen and methane blends including pure …

In this paper we investigate the effects of increasing the amount of hydrogen in the fuel
mixture on the stability of a perfectly premixed combustor. Experiments are carried out on a …

Numerical simulations were used to characterise the non-linear response of a turbulent
premixed flame to acoustic velocity fluctuations. The test flame simulated was the bluff body …

A coupled numerical approach is investigated for predicting combustion instability limit cycle
characteristics when the combustor contains a long flame. The test case is the ORACLES …

Thermoacoustic phenomena generated inadvertently during combustion, and those
produced by heating and cooling material to generate a temperature gradient, have mostly …

This work analyzes pressure and hydrogen enrichment effects on the stabilization and
combustion dynamics of a partially-premixed swirled-stabilized methane flame operated at …
