Recent developments in numerical schemes, turbulent combustion models and the regular
increase of computing power allow Large Eddy Simulation (LES) to be applied to real …

This article proposes a review of the state of knowledge in the field of combustion noise. The
survey comprises an initial discussion of indirect and direct noise sources and their general …

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 turbulent flow within a complex swirled combustor is studied with compressible large
eddy simulation (LES), acoustic analysis, and experiments for both cold and reacting flows …

While most academic set ups used to study combustion instabilities are limited to single
burners and are submitted mainly to longitudinal acoustic modes, real gas turbines exhibit …

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) …

Nitric oxide formation in gas turbine combustion depends on four key factors: flame
stabilization, heat transfer, fuel–air mixing and combustion instability. The design of modern …

Cavitation bubble collapse close to a submerged sphere on a microscale is investigated
numerically using a finite volume method in order to determine the likelihood of previously …

Abstract Large Eddy Simulation (LES) is a fundamental research tool to study gas turbines
and aero-engine combustors. In LES, although rarely addressed systematically, it is known …

The entropy noise mechanism was investigated both experimentally and numerically on a
generic test case. The model experiment features electrical heating to generate non …
