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 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 …

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 …

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 …

Swirling flame dynamics is investigated using a radial swirler equipped with movable
blades. This device allows to continuously change the swirl number and to examine various …

The interaction of a helical mode with acoustic oscillations is studied experimentally in a
turbulent swirl-stabilized premixed flame. In addition to a precessing vortex core (PVC), the …

We report on experimental and analytical studies of strongly swirling air flow in the near-field
of a generic axisymmetric tangential swirler used often as swirl generator in combustors …

This paper reports an experimental investigation of a non-reacting turbulent swirling flow in
a practical vortex combustor. The flow was examined for the conditions characteristic of the …

The dynamics of major flow structures were studied in a gas turbine model combustor for
perfectly premixed swirl-stabilized flames under a variety of reacting and non-reacting …

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 …
