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:

Conservative averaging method for solving some nonlinear heat transfer problems related to combustion
TL;DR: In this article, the authors considered a nonlinear heat transfer problem related to combustion and proved the coincidence of the exact solution of the studied boundary value problem with the approximate solution, the designed exponential type spline function is proved.
Normalising particle-distribution biases using jet injection
TL;DR: In this paper, a two-phase jet flow with a controlled initial bias is generated and various strategies are explored to correct this bias using planar nephelometry, which is a planar imaging technique using Mie-scattering.

Swirl combustor flow visualization studies in a water tunnel
TL;DR: In this article, a swirl combustor with a confinement ratio of 1.0, secondary downstream injection, aspiration holes, and a large central hub was simulated, and data was collected from visualization with neutral density plastic beads.

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.
