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:

Lean blow-off characteristics of a tangential entry type dual swirling free and impinging flame
Girish Sapra,Subhash Chander +1 more
TL;DR: In this article, an experimental study has been carried out to investigate the lean blow-off (LBO) characteristics of a tangential entry type dual swirling flame under different operating and geometrical parameters.
The Effect of Centerline Enrichment for Flexible Low Swirl Burner Flame Stabilization
TL;DR: Leong et al. as discussed by the authors proposed a geometrically flexible low swirl burner (LSB) flame stabilization system using a centerline pilot to induce local fuel enrichment from a small percentage of the load to improve performance.
Investigation of gas swirl burner characteristic on biomass gasification system using combustion unit equipment (cue)
TL;DR: In this article, the authors explored the flame characteristics of low-swirl burners, especially using low calorific gas produced by a biomass gasification system, and the results indicated that swirl vanes with 8 blades and diameter of 55 mm perform better than other number of blades of swirl vane burners.

Dynamics and bifurcations of laminar annular swirling and non-swirling jets
TL;DR: In this paper , bifurcation analyses characterising the nonlinear dynamics of fully developed laminar annular jets with respect to the centerbody diameter, Reynolds number, and swirl ratio are presented.

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.
