This paper presents bifurcation analyses characterising the nonlinear dynamics of fully
developed laminar annular jets with respect to the centrebody diameter is increased …

Axisymmetric numerical simulations are used to assess the swirl-induced stabilization of low-
Mach-number non-premixed jet flames at a moderate Reynolds number (R e= 200). Using a …

In this study, three-dimensional flow structures at a Reynolds number of 16 000 are
measured by stereoscopic particle image velocimetry to reveal the dynamic structures of a …

In open flow simulations, the dispersion characteristics of disturbances near synthetic
boundaries can lead to unphysical boundary scattering interactions that contaminate the …

Vortex Breakdown (VB) phenomena in swirling sudden expansion flows result in complex
coherent structures, like a Precessing Vortex Core (PVC), and hysteretic behavior as a …

In combustion applications such as gas turbines, swirling jets are used to generate a vortex
breakdown recirculation region that serves as a non-invasive flame stabilizer. The present …

Using three-dimensional numerical simulations, we analyze the entrainment of the ambient
fluid at the interface of a swirling liquid jet for swirl numbers of 0.5≤ S≤ 1.55 and moderate …

Three-dimensional swirling flow structures in a confined chamber, generated by an axial
swirler with different swirl numbers S (0.461, 0.799, 1.384), are experimentally investigated …

Swirling jets are commonly used in the burners of gas turbines to enhance mixing or to
stabilize the flames. In this manuscript, a stereo (3C2D) particle image velocimetry (SPIV) …
