Holes in flames, flame isolas, and flame edges
Proceedings of the Combustion Institute, 2000We examine a simple model problem designed to elucidate how easily a hole in a diffusion flame can close and how easily an isolated region of burning in a mixing region (a flame isola) can grow. With the thickness of the mixing layer/diffusion flame defining the characteristic length, we find that a hole of diameter ≈1 closes for all but a tiny ...

Flame jet properties of Bunsen-type flames
Combustion and Flame, 2006The flame jet width and flame jet velocity of the burnt gases of a premixedBunsen-type flame are important parameters to quantify the heat transfer rate ofthese flames.In this paper a simple expression is derived to estimate the resulting flame jetwidth and flame jet velocity of burnt gases of a free flame afterexpansion over the flame front for the ...

Stratified turbulent Bunsen flames: flame surface analysis and flame surface density modelling
Combustion Theory and Modelling, 2012In this paper it is investigated whether the Flame Surface Density (FSD) model, developed for turbulent premixed combustion, is also applicable to stratified flames. Direct Numerical Simulations (DNS) of turbulent stratified Bunsen flames have been carried out, using the Flamelet Generated Manifold (FGM) reduction method for reaction kinetics.

Non-premixed Flames (Diffusion Flames)
2011In many combustion processes, the fuel and oxidizer are separated before entering the reaction zone where they mix and burn. The combustion reactions in such cases are called “non-premixed flames,” or traditionally, “diffusion flames” because the transport of fuel and oxidizer into the reaction zone occurs primarily by diffusion.

Flames in vortices & tulip-flame inversion
2008This article summarises two areas of research regarding the propagation of flames in flows which involve significant fluid-dynamical motion [1]–[3]. The major difference between the two is that in the first study the fluid motion is present before the arrival of any flame and remains unaffected by the flame [1, 2] while, in the second study it is the ...
