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:

Investigation on flame characteristics of industrial gas turbine combustor with different mixing uniformities
TL;DR: In this paper, the combustion characteristics of SGT-100 combustor in three different mixing uniformities are studied by Large Eddy Simulation (LES) coupled Flamelet Generated Manifold (FGM) model.
Journal ArticleDOI
On numerical simulation of electromagnetic field effects in the combustion process
TL;DR: A simplified model taking into account the interplay of compressible, laminar, axisymmetric, and the electrodynamical effects due to Lorentz force’s action on the combustion process in a cylindrical pipe is presented.

Effects of air swirler geometry on air and spray droplet interactions in a spray chamber
TL;DR: In this paper, the interactions between cold spray and swirl airflow are characterized experimentally and numerically for various air swirler geometries, including the number of vanes, vane angle, and vane curvature.

On large eddy simulation of blended CH4–H2 swirling inverse diffusion flames: The impact of hydrogen concentration on thermal and emission characteristics
TL;DR: In this paper, a large eddy simulation (LES) was applied to investigate a mixture of CH 4 -H 2 swirling inverse diffusion flames, and the DLR-A benchmark was regarded as a reference to contrast Large Eddy Simulation and Unsteady Reynolds Averaged Simulation (URAS) predictions.
Journal ArticleDOI
The Formation and Evolution of Turbulent Swirling Vortex Rings Generated by Axial Swirlers
TL;DR: In this paper, the formation process and early stage evolution of turbulent swirling vortex rings are investigated by using planar Particle Image Velocimetry (PIV) and Large Eddy Simulation (LES).

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.
Journal ArticleDOI
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.
