Combustion LES for premixed and diffusion flames

Progress in Computational Fluid Dynamics, An International Journal, 2005
This paper demonstrates the ability of large-eddy simulation (LES) to accurately predict turbulent combustion. A non-premixed bluff-body flame was simulated, relying on the conserved scalar approach and the laminar flamelet concept. The results were found to agree well with experimental data.

DIFFUSION COMBUSTION AND ITS APPLICATION TO GLASSMELTING*

Journal of the American Ceramic Society, 1932
ABSTRACT Fuel gas may be burned as rapidly as possible by thorough premixing or as slowly as possible by the elimination of all effects tending to accelerate the mixture of air and gas. In the latter case, combustion occurs through molecular interdiffusion, hence, “diffusion combustion.” The diffusion flame has ...

The role of diffusion in the rapid combustion of cellulose

Proceedings of the Royal Society of London. A. Mathematical and Physical Sciences, 1984
Abstract Data that have been published previously for the combustion of cellulose under conditions of rapid heating are analysed in terms of transport processes. Calculations of Reynolds numbers indicate that the flow régime close to the burning cellulose surface is laminar or laminary.

Magnetic promotion of combustion in diffusion flames

Combustion and Flame, 1993
Inhomogeneous magnetic fields have been found to promote combustion reactions in diffusion flames. When a fuel gas flowed in the direction of a decreasing field strength, the burning velocity was found to increase. No magnetic effect was observed when it flowed into a homogeneous field.

Methane Combustion in Laminar Diffusion Flames

Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power Engineering, 1989
This paper is concerned with methane combustion in laminar diffusion flames. Data on methane concentration distributions in different diffusion flame geometries are correlated against a conserved scalar called mixture fraction. The correlation is used to determine a global methane combustion rate applicable in the rich to stoichiometric regions of ...

Reaction-diffusion fronts in heterogeneous combustion

2011
Heterogeneous flames are modeled in a simplified system where the fuel particles are discrete heat sources embedded in an inert, heat conducting medium. Two asymptotic regimes of flame propagation are found and exhibit differences in both the propagation limits and the front speeds.
