Preferential diffusion effects in diffusion flames
2008Numerical computations were made of axisymmetric laminar jet diffusion flames taking into account detailed chemical kinetics and multicomponent diffusion. It was shown that preferential diffusion of heat and species causes significant amount of excess and deficit of enthalpy, and increase and decrease of mole fraction in the flame. These effects result

Symposium (International) on Combustion, 1973
Experimental results are presented for turbulent diffusion flames of a round jet of hydrogen in a co-flowing stream of air. The aim of the work is to provide comprehensive data which will assist in refining the newer and more-powerful theories coming into use.

BURNER flames of unusual structure may be obtained when certain hydrocarbon gases and vapours are burnt in admixture with air or oxygen. Thus, as first noted by Smithells and Ingle1, and later by Smith and Pickering2, the inner cones of the flames may assume the form of a polyhedron, the number of sides of which is dependent upon prevailing conditions,

The Structure of Diffusion Flames
Combustion Science and Technology, 1976Abstract The theory for the mixing and chemical reaction of two streams of fluid is developed for unsteady laminar and for turbulent flow. Only one conserved scalar is required to fully describe the mixing and various reaction models are considered including the Burke-Schumann flame sheet and shifting equilibrium.

Instability of diffusion flames
Symposium (International) on Combustion, 1996The constant frequency oscillation of buoyant jet diffusion flames is a phenomenon that has been studied extensively during the past three decades. In recent experimental and theoretical works, the coherent flow field and flame structures were analyzed successfully.

Nine classic diffusion flames, i.e., combustion systems with initially separate fuel and oxidizer, are synthesized in a search for common dimensionless parameters which may serve as indice of fire hazard. The problems examined are: planar and cylindrical Burke-Schumann; droplet burning; planar and cylindrical stagnant film; and forced, free, mixed, and
