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 paper investigates one issue related to Large Eddy Simulation (LES) of self-excited
combustion instabilities in gas-fueled swirled burners: the effects of incomplete mixing …

COMBUSTION oscillations are frequently encountered during the development of many
combustion chambers for gas turbines [1–4]. To date, these oscillations cannot be predicted …

The interaction of a helical mode with acoustic oscillations is studied experimentally in a
turbulent swirl-stabilized premixed flame. In addition to a precessing vortex core (PVC), the …

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) …

Although Large Eddy Simulations (LES) have demonstrated their potential in simple
academic combustion chambers, their application to real gas turbine chambers requires …

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 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 …

Great prominence is put on the design of aeronautical gas turbines due to increasingly
stringent regulations and the need to tackle rising fuel prices. This drive towards innovation …
