Combustion instability remains a critical issue limiting the development of low-emission,
lean-premixed (LPM) gas turbine combustion systems. The present work provides a …

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 paper presents recent progress in the field of thermoacoustic combustion instabilities in
propulsion engines such as rockets or gas turbines. Combustion instabilities have been …

Large-eddy simulation (LES) of turbulent combustion is a relatively new research field. Much
research has been carried out over the past years, but to realize the full predictive potential …

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 …

A detailed analysis of the flow–flame interactions associated with acoustically coupled heat-
release rate fluctuations was performed for a 10kW, CH4/air, swirl stabilized flame in a gas …

Being able to ignite or reignite a gas turbine engine in a cold and rarefied atmosphere is a
critical issue for many manufacturers. From a fundamental point of view, the ignition of the …

The impact of burned gases on flame stabilization is analyzed under the conditions of a
laboratory jet flame in vitiated coflow. In this experiment, mass flow rate, temperature, and …

Methane and hydrogen-enriched (25 vol% and 50 vol% H 2-enriched CH 4) methane/air
premixed flames were investigated in a gas turbine model combustor under atmospheric …

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