In this paper, we apply the novel EPTD (Exceptional Point-based Thermoacoustic Design)-
method derived in part I of this study (M. Casel & A. Ghani, Combust. Flame, 2024) to two lab …

This article reports experiments carried out in the laboratory scale annular combustor
MICCA-spray equipped with multiple swirling spray injectors. The experimental setup …

Acoustic waves can affect the heat release of a flame, also and any disturbance in the heat
release of a flame will cause the production of pressure waves. If the acoustic field and heat …

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 …

Flame structure can have a significant effect on a combustor's static stability (resistance to
blowoff) and dynamic stability (combustion instability) and therefore is an important aspect of …

Incoming standards on NO x emissions are motivating many aero-engine manufacturers to
adopt the lean burn combustion concept. One of the most critical issues affecting this kind of …

The development of lean-burn combustion systems is of paramount importance for reducing
the pollutant emissions of future aero engine generations. By tilting the burners of an …

This work proposes a novel methodology to extract useful information on flame dynamics
from instantaneous chemiluminescence images in terms of the 'effective local response', by …

In most modern-day lean gas turbine combustors, flame is stabilized by swirl flows. A central
toroidal recirculation zone (CTRZ), developed by these swirl flows, helps to stabilize the …

The flame transfer function (FTF) has been experimentally investigated for a premixed,
turbulent and highly swirled flame in rectangular enclosures with varying aspect ratio. A …
