This paper reviews the studies undertaken on vortex breakdown over the past 45 years. The
paper is structured such that the area is considered in three sections—experimental …

▪ Abstract The paper reviews striking features of swirling flows—collapse, swirl generation,
vortex breakdown, hysteresis, and axisymmetry breaking—and the mechanisms involved …

This paper provides a new study of the axisymmetric vortex breakdown phenomenon. Our
approach is based on a thorough investigation of the axisymmetric unsteady Euler …

Laser Doppler velocimetry (LDV) measurement and large eddy simulation (LES) were used
to study confined isothermal turbulent swirling flows in a model dump combustor. The aim …

A numerical investigation of steady states, their stability, onset of oscillatory instability, and
slightly supercritical unsteady regimes of an axisymmetric swirling flow of a Newtonian …

The nature of the vortex end (or the “tail end” or “tip”) in reverse-flow centrifugal gas cleaning
equipment, cyclones and swirl tubes, has been studied by visualization using a stroboscope …

A common element in physiological flow networks, as well as most domestic and industrial
piping systems, is a T junction that splits the flow into two nearly symmetric streams. It is …

This paper explains hysteretic transitions in swirling jets and models external flows of vortex
suction devices. Toward this goal, the steady rotationally symmetric motion of a viscous …

This work examines the flow and mixing in selected non-premixed cases of the Sydney Swirl
Flame series by Large Eddy Simulation. A mixture fraction approach with a steady flamelet …

This paper characterises the steady and time-periodic behaviour of swirling jets using
numerical bifurcation analysis. Its objective is to elucidate the dynamics of fully developed …
