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:

Experimental investigation of lean-dome high-airflow airblast pilot mixers' operability, emissions, and dynamics
TL;DR: In this article, the authors investigated the effect of the outer swirler vane angle on LDI reacting flow characteristics and showed that the inclusion of a flare significantly increases the overall swirl strength of the injector.

Swirling flow effect on film cooling performance downstream of a sudden expansion
Chie Gau,K. A. Yih,S. S. Chang +2 more
TL;DR: In this article, the film cooling effectiveness in a film cooled circular pipe downstream of an abrupt 2.4:1 expansion with the presence of weak swirling flow in the mainstream was investigated.

Guiding Actuator Designs for Active Flow Control of the Precessing Vortex Core by Adjoint Linear Stability Analysis
TL;DR: In this paper, an open-loop actuation is applied in the mixing section between the swirler and the generic combustion chamber of a non-reacting swirling jet setup to investigate the receptivity of the precessing vortex core with regard to its lock-in behavior at different streamwise positions.

Global hydrodynamic instability and blowoff dynamics of a bluff-body stabilized lean-premixed flame
Manikandan Balasubramaniyan,Abhijit Kumar Kushwaha,Yu Guan,Jianchang Feng,Peijin Liu,Vikrant Gupta,Larry K.B. Li +6 more
TL;DR: In this paper, a lean-premixed flame stabilized behind a circular cylinder is investigated, and it is shown that the flame transitions from a steady mode to a varicose mode and then to a sinuous mode.

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.
