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 …

Thermoacoustic instability is a flow instability that arises due to a two-way coupling between
acoustic waves and unsteady heat release rate. It can cause damaging, large-amplitude …

This paper presents recent progress in the field of thermoacoustic combustion instabilities in
propulsion engines such as rockets or gas turbines. Combustion instabilities have been …

The present work introduces an annular combustion chamber operated at intermediate
pressures. The combustor is operated with CH 4-H 2 blends leading to a variety of azimuthal …

This article reports a numerical analysis of combustion instabilities coupled by a spinning
mode or a standing mode in an annular combustor. The method combines an iterative …

Can-to-can acoustic interactions in a circumferential network of lean-premixed combustors
have a prominent role in the development of complicated modal dynamics and large-scale …

modes in annular chambers | Physics of Fluids | AIP Publishing Skip to Main Content …

Thermo-acoustic instabilities in annular combustors equipped with swirling turbulent
injectors are most often coupled by azimuthal modes with a spinning or a standing structure …

Practical passive control solutions for azimuthal thermoacoustic instabilities in annular
combustors, which typically involve symmetry-breaking strategies, have garnered increasing …

This article deals with the symmetry breaking of azimuthal thermoacoustic modes in annular
combustors. Using a nominally symmetric annular combustor, we present experimental …
