Vortex breakdown (VB) in unconfined swirling jets occurs as either a bubble form of vortex
breakdown (BVB) or a conical form of vortex breakdown (CVB). This computational study …

This paper characterises the steady and time-periodic behaviour of swirling jets using
numerical bifurcation analysis. Its objective is to elucidate the dynamics of fully developed …

Modern low-emissions gas turbine combustors commonly employ a twin annular swirling
flow configuration that consists of a central annular inner jet and a surrounding annular outer …

Abstract About 140 years ago, Lord Kelvin derived the equations describing waves that
travel along the axis of concentrated vortices such as tornadoes. Although Kelvin's vortex …

The topology and the dynamics of Vogel–Escudier flow, which is the flow inside a circular
cylinder with a top rotating lid, are presented in this paper. A three-dimensional direct …

We analyze the successive steps of the breakup morphology of a swirling liquid jet. Three-
dimensional numerical simulations are carried out using the Volume of Fluid method with …

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 …

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 …
