Theoretical Analysis of Nitric Oxide Production in a Methane/Air Turbulent Diffusion Flame [PDF]
, 1980 The coherent flame model is applied to the methane-air turbulent diffusion flame with the objective of describing the production of nitric oxide. The example of a circular jet of methane discharging into a stationary air atmosphere is used to illustrate ...

Experiments in a novel quasi-1D diffusion flame with variable bulk flow [PDF]
Proceedings of the Combustion Institute 32 (1), 987-994, 2009The novel species injector of a recently developed research burner, consisting of an array of hypodermic needles, which allows to produce quasi one-dimensional unstrained diffusion flames has been improved. It is used in a new symmetric design with fuel and oxidizer injected through needle arrays which allows to independently choose both the magnitude ...

Effect of heat release on the spatial stability of a supersonic reacting mixing layer [PDF]
A numerical study of the stability of compressible mixing layers in which a diffusion flame is embedded is described. The mean velocity profile has been approximated by a hyperbolic tangent profile and the limit of infinite activation energy taken, which

Diffusion-controlled combustion [PDF]
, 2001 We devote this brief review to some relevant aspects of diffusion-controlled combustion. After a survey of the conservation equations involved, we shall describe the Burke-Schumann limit, which is applicable when the reaction time at the flame is very ...

An Experimental and Theoretical Study of Radiative Extinction of Diffusion Flames [PDF]
In a recent paper on 'Observations of candle flames under various atmospheres in microgravity' by Ross et al., it was found that for the same atmosphere, the burning rate per unit wick surface area and the flame temperature were considerably reduced in ...

A simple model of mixing and chemical reaction in a turbulent shear layer [PDF]
, 1981 Arguments are presented to show that the concept of gradient diffusion is inapplicable to mixing in turbulent shear layers. A new model is proposed for treating molecular mixing and chemical reaction in such flows at high Reynolds number.
