Combustion is an essential process for generating propulsion for most existing aircraft. The combustion processes, such as ignition, flame propagation, and flame stability, are …
Methane–ammonia mixtures have potentials as low-carbon fuels for gas turbines, however significantly high fuel NOx production in their flames present challenges to their application …

The advances in computing power and numerical schemes allow Large Eddy Simulation (LES) to use more detailed turbulent combustion models as well as to be applied to real gas …
We investigate the onset of thermo-acoustic instabilities and their link to the mean flame configurations–or macrostructures–under acoustically coupled and decoupled conditions …
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 …
Complying with stringent pollutant emission regulations requires a strong optimization of modern gas turbine combustors, for which Large Eddy Simulation (LES) is a promising tool …
