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 …

The phase-averaged velocity distributions were applied for calculation of parameters of a
precessing vortex core; these were the input data for calculation of precession frequency by …

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 …

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 …

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 a detailed investigation of the interaction between a wall-bounded
precessing vortex core (PVC) occurring in swirling flows after vortex breakdown and a wall …

The precessing vortex core (PVC) is a coherent structure that can arise in swirling jets from a
global instability. In this work, the PVC is investigated under highly turbulent conditions. The …

Precessing vortex core (PVC), a typical vortex structure, universally exists in swirling flow
fields and originates from the Kelvin–Helmholtz instability of the swirling shear layer. In the …

Recently, the particular energy separation of the vortex tube was thought to be caused by
the energy transferred from the inner core stream to the outer periphery stream through the …

Particle image velocimetry (PIV) measurements are made in a highly turbulent swirling flow.
In this flow, we observe a coexistence of turbulent fluctuations and an unsteady swirling …
