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 …

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 …

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 …

Numerical simulation of a dual-swirl gas turbine model combustor is performed under cold
and reacting flow conditions using a three-dimensional unsteady Reynolds-averaged Navier …

Oscillating heat release associated with large-scale vortex structures in a dump combustor
was investigated experimentally. The objectives were to understand vortex–heat release …

The PRECCINSTA GTMC was studied at elevated pressure and power density with 6 kHz
stereoscopic particle image velocimetry (SPIV), OH* chemiluminescence (CL), and 100 kHz …

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 …

The precessing vortex core (PVC) is a helically shaped coherent flow structure that occurs in
reacting and nonreacting swirling flows undergoing vortex breakdown. In swirl-stabilized …

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 …
