On the dynamics of the collapse of a diffusion-flame hole [PDF]
, 2003 The collapse dynamics of a diffusion-flame hole in the presence of a counterflow are studied. We construct unsteady solutions of the one-dimensional edge-flame model of Buckmaster (1996), in which heat and mass transverse losses are algebraic.

Modelling and control of the flame temperature distribution using probability density function shaping [PDF]
, 2006 This paper presents three control algorithms for the output probability density function (PDF) control of the 2D and 3D flame distribution systems. For the 2D flame distribution systems, control methods for both static and dynamic flame systems are ...

The Sivashinsky equation for corrugated flames in the large-wrinkle limit [PDF]
, 2008 Sivashinsky's (1977) nonlinear integro-differential equation for the shape of corrugated 1-dimensional flames is ultimately reducible to a 2N-body problem, involving the 2N complex poles of the flame slope.

On the dynamics of flame edges in diffusion-flame/vortex interactions [PDF]
Combustion and Flame, 2007 We analyze the local flame extinction and reignition of a counterflow diffusion flame perturbed by a laminar vortex ring. Local flame extinction leads to the appearance of flame edges separating the burning and extinguished regions of the distorted mixing layer.
