Thermoacoustic oscillations associated with transverse acoustic modes are routinely
encountered in combustion chambers. While a large literature on this topic exists for rockets …

Since its birth in the 1920s, quantum mechanics has motivated and advanced the analysis of
linear operators. In this effort, it significantly contributed to the development of sophisticated …

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 …

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 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 …

The objectives of this paper are the description of azimuthal instability modes found in
annular combustion chambers using two numerical tools:(1) Large Eddy Simulation (LES) …

In this paper we describe the time-varying amplitude and its relation to the global heat
release rate of self-excited azimuthal instabilities in a simple annular combustor operating …

This paper deals with the dynamics of standing and rotating azimuthal thermoacoustic
modes in annular combustion chambers. Simultaneous acoustic measurements have been …

Lean premixed combustion chambers are susceptible to combustion instabilities arising
from the coupling between the heat release rate perturbations and the acoustic …

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 …
