Effects of swirl divergence cup and the central bluff body on premixed flame response with
external excitation are experimentally investigated. Flame transfer functions (FTFs) …

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

Global instabilities in swirling flows can significantly alter the flame and flow dynamics of
swirl-stabilized flames, such as those in modern gas turbine engines. In this study, we …

Precessing vortex core (PVC), a typical vortex structure, universally exists in swirling flow
fields and originates from the Kelvin–Helmholtz instability of the swirling shear layer. In the …

To improve hydrodynamic stability in a combustor, an unsteady flow analysis method is
needed. Hence, the proper orthogonal decomposition (POD) method based on a large eddy …

A precessing vortex core (PVC) is a self-excited helical instability that results from the
precession of the vortex core around the flow axis in the upstream region of a vortex …

Predicting and perhaps mitigating against rare, extreme events in fluid flows is an important
challenge. Due to the time-localised nature of these events, Fourier-based methods prove …
