The precessing vortex core (PVC) is a coherent flow structure that is often encountered in
swirling flows in gas turbine (GT) combustors. In some swirl combustors, it has been …

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

This report deals with an experimental and analytical study of the occurrence of self-excited
hydrodynamic instabilities in swirling combustor flows. Different flow field types are …

This paper reviews the occurrence of the precessing vortex core (PVC) and other
instabilities, which occur in, swirl combustion systems whilst identifying mechanisms, which …

The interaction of a helical precessing vortex core (PVC) with turbulent swirl flames in a gas
turbine model combustor is studied experimentally. The combustor is operated with air and …

Linear stability analysis is applied to a swirl-stabilized combustor flow with the aim to
understand how the flame shape and associated density field affects the manifestation of …

The flow patterns produced in and past the exhaust of a 100-KW swirl burner have been
investigated experimentally under piloted premixed combustion conditions. The well-known …

In this study, a combined experimental and Large Eddy Simulation (LES) investigation is
performed to identify the vortical structures, their dynamics, and interaction with a turbulent …

The mechanisms of the interaction between a precessing vortex core (PVC) and a turbulent
swirl flame in a gas turbine model combustor are investigated experimentally using …

In many continuous combustion processes the flame is stabilized by swirling the injected
flow. This is the case for example in aeroengine combustors or in gas turbines where …
