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:

Numerical and experimental study of flow structure and heat release distribution in a stratified swirl flame with high-speed PIV and OH* measurements
Sheng Meng,Shizhi Wu,Man Zhang +2 more
TL;DR: In this paper, the authors employed large eddy simulation (LES) combined with a detailed OH* chemiluminescence reaction mechanism to validate the chemilumininescent image of OH* in a stratified swirled flame at the atmosphere condition.

Investigation of Economical Design Strategies for the Solid Oxide Fuel Cell Afterburner Based on Computational Fluid Dynamics Simulation
Junkyu Park,Shin Hyuk Kim +1 more
TL;DR: In this paper , the authors simulate the computational fluid dynamics (CFD) to explore the design optimization strategies of the solid oxide fuel cell (SOFC) afterburner, which is carried out with the eddy dissipation concept (EDC), applying a three-step rate-dependent reaction mechanism to predict the determining step of the combustion reactions by changes of the control and design parameters.

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.
