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:

Effect of varying the double radial swirler configuration on the fluid dynamic and emissions performances in a can combustor
TL;DR: In this article, the authors presented the fluid dynamic and combustion performances of a can combustor applying double radial flow swirler and compared with experimental works conducted by previous researchers using Computational Fluid Dynamics simulation (CFD).

Velocity field characteristics of a swirling flow combustor
TL;DR: In this article, a closed, central recirculation zone is observed in both swirl conditions for reacting flow, but only in counterswirl for non-reacting flow in a combustor consisting of two confined, concentric swirling jets.

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.
