Combustion in swirling flows: A review
Nicholas Syred,János M. Beér +1 more
TLDR
The main effects of swirl are to improve flame stability as a result of the formation of toroidal recirculation zones and to reduce combustion lengths by producing high rates of entrainment of the ambient fluid and fast mixing as discussed by the authors.About:

Flame Spectra of a Turbulent Liquid-Fueled Swirl-Stabilized Lean-Direct Injection Combustor
Tongxun Yi,Domenic A. Santavicca +1 more
TL;DR: In this article, the authors measured the flame spectra of a turbulent, liquid-fueled, swirl-stabilized, lean-direct injection combustor and determined the instantaneous heat release rate and equivalence ratio along the flame front.

Laser-based particle measurements of spherical and nonspherical particles
David Lee Black,M.Q. McQuay +1 more
TL;DR: In this paper, the authors collected a detailed set of particle information in a co-axial jet and a swirling flow to assess the influence of particle shape on the particle dynamics.

Active Control of Swirling Coaxial Jet Mixing with Manipulation of Large-Scale Vortical Structures
TL;DR: In this article, the outer shear layer of the outer swirling coaxial jet with miniature flap actuators was investigated using stereo-PIV and plannar laser-induced fluorescence (PLIF) techniques.

Theory of the vortex breakdown phenomenon
TL;DR: In this paper, it is shown that vortex breakdown is not a manifestation of instability or of any other effect indicated by study of infinitesimal disturbances alone, but instead a finite transition between two dynamically conjugate states of axisymmetric flow, analogous to the hydraulic jump in open-channel flow.

On stationary and travelling vortex breakdowns
TL;DR: In this article, the authors describe some experiments in swirling flows in a diverging cylindrical tube in which various types of vortex breakdowns were observed, viz. mild (double helix) breakdown, spiral breakdown, and axisymmetric breakdown.

Some observations of the vortex breakdown phenomenon
TL;DR: In this article, a cylindrical vortex, formed in a long tube, was used to study the "vortex breakdown" that has been previously reported in investigations of the flow over slender delta wings.
