This paper presents an experimental study on the emergence of the central recirculation
zone (CRZ) in a basic V-shaped premixed swirling flame, using simultaneous measurement …

The unsteadiness due to tip leakage vortex (TLV) breakdown was studied using a special
experimental test campaign in parallel with numerical simulations. The back flow vortex …

Unsteady axisymmetric numerical simulations are used to determine the transition to bubble
and conical vortex breakdown in low-Mach-number laminar swirling Burke–Schumann …

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 …

This paper explores the effect of axial and radial confinement on the flow topology of laminar
swirling jets. Its objective is to provide a unifying perspective toward swirling jet mechanics …

The current work investigates the transition of a swirling jet between two flow states, namely,
columnar-jet (CJ) and wall-jet (WJ) states, under the influence of external transverse …

We investigate the effect of transverse acoustic excitation on nonreacting swirling jets. The
work is motivated by the azimuthal instabilities in annular gas turbine combustor which are …

A flame's structural feature is a crucial parameter required to comprehensively understand
the interaction between turbulence and flames. The generation and evolution processes of …

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 …
