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 presents the results of a parametric experimental study of free swirling flow at the
exit of a flat-vane axial swirler. A total of 16 data sets were acquired by combining four …

An experimental analysis of the precessing vortex core (PVC) instability in a free swirling jet
of air at ambient pressure and temperature is performed by means of laser Doppler …

This paper presents an experimental study of a strongly swirling turbulent flow with the
formation of a precessing vortex core (PVC) that emerges at the outlet of a tangential swirler …

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

Large scale coherent structures play an important role in the behavior of the combustion
regime inside any type of combustor stabilized by swirl, with special impact on factors such …

Confined turbulent air swirling flows are investigated for two configurations where swirl is
produced by a conventional radial type swirler. The flow Reynolds number based on the …

In this paper, we study the flow structures and associated dynamics of an annular swirling jet
in the transitional flow regime at Re= 520. In literature, studies on fully laminar or turbulent …

Swirler design strongly influences combustion stabilization and flame dynamics in gas
turbines. The rotating flow induced by the swirler is mainly determined by the swirl number …

This paper describes recent work at Cardiff to gain further understanding of the fundamental
processes occurring in swirl burners. The phenomenon of the precessing vortex core has …
