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:

Numerical and Experimental Analysis of the Effect of a Swirler with a High Swirl Number in a Biogas Combustor
Marco Osvaldo Vigueras-Zúñiga,Carlos Augusto Ramírez-Ruíz,Agustín L. Herrera-May,María Elena Tejeda-del-Cueto +3 more
TL;DR: In this paper, a simulation of combustion with biogas in a combustion chamber is presented, where an optimized swirler in the airstream with a swirl number (Sn) of 2.48 is used.

Experimental Investigation of Flow and Wall Heat Transfer in an Optical Combustor for Reacting Swirl Flows
TL;DR: Experimental Investigation of Flow and Wall Heat Transfer in an Optical Combustor for Reacting Swirl Flows as discussed by the authors, showed that flow and wall heat transfer in an optical combustor can be used for cooling swirl flows.

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.
