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 article describes recent progress on premixed flame dynamics interacting with acoustic
waves. Expressions are derived to determine the stability of combustors with respect to …

The present article investigates the interactions between the pilot and main flames in a novel
stratified swirl burner using both experimental and numerical methods. Experiments are …

The crux of the technical issues facing the development of hydrogen gas turbine engines is
the problem of how to enable low NOx, low dynamics combustor operations without …

The dynamics of V-shape swirled lean premixed methane/air flames enriched with hydrogen
is examined for two injection schemes. The response of the flames submitted to harmonic …

This conceptual numerical study explores a possible strategy for control of unstable intrinsic
thermoacoustic (ITA) modes. Control of the ITA feedback loop has not been discussed yet …

Ammonia is a promising hydrogen and energy carrier but also a challenging fuel to use in
gas turbines, due to its low flame speed, limited flammability range, and the production of …

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 …

Domestic condensing boilers are equipped with perforated burners ensuring short-length
premixed flames issues from a series of circular holes and slits. Despite some efforts that …

The response to forcing of a 2D laminar premixed slot flame is investigated by means of
linear analysis, based on the compressible flow equations with a two-step reaction scheme …
