Lean blowout (LBO) of a partially premixed swirl flame is studied using chemiluminescence
imaging and simultaneous stereo-PIV and OH-PLIF measurements at repetition rates up to …

The lift-off mechanism of swirl stabilized premixed flames was investigated using high
repetition rate OH planar laser induced fluorescence (PLIF), particle image velocimetry …

An understanding of the amplitude dependence of the flame response to harmonic acoustic
excitation is required in order to predict and/or correlate combustion instability amplitudes …

The present work addresses unsteady flame dynamics in a lean-premixed swirl-stabilized
combustor, with attention focused on the transition of flame structure from a stable to an …

A laboratory-scale swirling burner, presenting many similarities with gas turbines
combustors, has been studied experimentally using planar laser induced fluorescence …

Modern low-emission, lean premixed gas turbine combustion systems often rely on confined
swirling flows associated with sudden expansions to enhance flame anchoring. Through the …

The dynamics of major flow structures were studied in a gas turbine model combustor for
perfectly premixed swirl-stabilized flames under a variety of reacting and non-reacting …

Towards the implementation of alternative jet fuels in aviation gas turbines, testing in
combustor rigs and engines is required to evaluate the fuel performance on combustion …

Abstract Large Eddy Simulations (LES) are used to study a lean swirl-stabilized gas turbine
burner where the flow exhibits two stable states. In the first one, the flame is attached to the …
