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:

Application of Oxy-fuel Combustion Technology into Conventional Combustors
TL;DR: Amponsah et al. as mentioned in this paper showed that by the year 2050, the emission levels of CO2 are expected to be increased by about 70% compared to the present levels.

Film cooling performance and flow structure of single-hole and double-holes with swirling jet
TL;DR: In this paper , a numerical study of the effects of swirling flow in coolant jets on film cooling performance is presented. And the results show that film cooling effectiveness is improved with jet swirl at high blowing ratios.

Investigation on the Turbulent Swirling Flow Field within the Combustion Chamber of a Gun-Type Gas Burner
TL;DR: In this paper, the turbulent swirling flow field in the edge of a jet seems to cause a recirculation flow from downstream to upstream due to the unbalance of static pressure between a main jet flow and a chamber wall.

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.
