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 …

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 …

In this paper, we investigate the flow structures and pressure fields of a free annular swirling
jet flow undergoing vortex breakdown. The flow field is analyzed by means of time-resolved …

Entrainment is of crucial importance in many engineering applications, while the relevance
of swirling flows is related to their ability to improve mixing in the initial region of a jet, as a …

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 …

Large-scale organized vortical structures were studied experimentally in a free swirling jet of
air experiencing vortex precession (PVC) at ambient conditions. Detailed measurements …

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 …

We study the emergence of precessing vortex core (PVC) oscillations in a swirling jet
experiment. We vary the swirl intensity while keeping the net mass flow rate fixed using a …

SWIRLING jet flows are used in many applications including combustion and separation
control as a result of their unique flowfield properties. In addition, swirling jet flows are …
