Thermo-acoustic instabilities in lean premixed swirl-stabilized combustion and their link to acoustically coupled and decoupled flame macrostructures
Abstract We investigate the onset of thermo-acoustic instabilities and their link to the mean flame configurations – or macrostructures – under acoustically coupled and decoupled conditions.… Expand

Turbulent flame stabilization modes in premixed swirl combustion: Physical mechanism and Karlovitz number-based criterion
Abstract 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… Expand

Impact of fuel and oxidizer composition on premixed flame stabilization in turbulent swirling flows : dynamics and scaling
The world relies on fossil fuels as its main energy source (86.7% in 1973, 81.7% in 2012 1). Several factors including the abundance of resources and the existing infrastructure suggest that this is… Expand

The structure of swirl-stabilized turbulent premixed CH4/air and CH4/O2/CO2 flames and mechanisms of intense burning of oxy-flames
Abstract The objective of this work is to examine the structure of lean turbulent premixed CH 4 /air (air-flames) and CH 4 /O 2 /CO 2 (oxy-flames) in a swirl-stabilized combustor at the large (macro)… Expand

Transition From a Single to a Double Flame Structure in Swirling Reacting Flows: Mechanism, Dynamics, and Effect of Thermal Boundary Conditions
We examine experimentally the transition from a single flame stabilized along the inner shear layer (ISL) to a double flame stabilized along both the inner and the outer shear layers (OSL) and… Expand
