Experimental and theoretical investigation of the flashback of a swirling, bluff-body stabilised, premixed flame [PDF]
, 2015 Flashback of an open turbulent, premixed flame in a swirl burner with central bluff-body is considered. The aim is to obtain further understanding of the physical mechanisms responsible for the upstream flame propagation.

Formation of corner waves in the wake of a partially submerged bluff body [PDF]
, 2015 We study theoretically and numerically the downstream flow near the corner of a bluff body partially submerged at a deadrise depth Δh into a uniform stream of velocity U, in the presence of gravity, g. When the Froude number, Fr=U/√gΔh, is large, a three-

Flow Interference in Bluff Body Wakes [PDF]
, 2003 This paper presents a two-dimensional numerical simulation of fluid flow around a couple of identical circular cylinders aligned, respectively, along and orthogonal to the main-flow direction, at several distances. A lattice-Boltzmann method (LB) is used.

Generation of adverse pressure gradient in the circumferential flashback of a premixed flame [PDF]
, 2016 Circumferential upstream propagation of a premixed flame in a region confined between two concentric tubes is considered. The cold flow in this configuration features rotational motion and the flame is modelled as an interface separating the burned and ...

Modal decomposition of fluid-structure interaction with application to flag flapping [PDF]
, 2017 Modal decompositions such as proper orthogonal decomposition (POD), dynamic mode decomposition (DMD) and their variants are regularly used to educe physical mechanisms of nonlinear flow phenomena that cannot be easily understood through direct inspection.
