Thermoacoustic instabilities under lean operation in gas turbine burners hinder the
development of lean premixed combustion mode of operation, thus limiting the potential to …

The coupling between fluid strain rate, local flame extinction, hydrodynamic instability, and
flame lift-off was studied in premixed swirl flames using multi-kHz repetition-rate OH …

The transient dynamics of the precessing vortex core (PVC), a globally unstable mode, in an
intermittently shape-transitioning swirl flame is investigated by means of simultaneous OH …

This work predicts the evolution of self-excited thermo-acoustic instabilities in a gas turbine
model combustor using large eddy simulation. The applied flow solver is fully compressible …

Large-eddy simulations of a sooting aero-engine model combustor are performed for three
operating points. They are analyzed to investigate the influence of secondary air injection …
