Progress in Energy and Combustion Science, 1982
Abstract Laminar counterflow diffusion flames are generally referred to as the pure diffusion flame. This paper reviews experimental studies of these counterflow diffusion flames and presents a detailed summary of our present understanding of them.

Turbulent Forced Diffusion Flames
Combustion and Flame, 1995A microscale, νβ ∼ νσβ13 is introduced for turbulent diffusion flames, where η and σβ respectively, are the Kolmogorov scale and the flame Schmidt number. In terms of this scale, the turbulent mass transfer integrated over a length l of a liquid fuel is shown to be M′= νBlνβ , where μ is the dynamic viscosity and B is the transfer number, B=(Y0∞

NEAR-LIMIT SPHERICAL DIFFUSION FLAMES AND COOL DIFFUSION FLAMES
2023To combat the rising threats of climate change, current combustion technologies must evolve to become cleaner and more efficient. This requires a better understanding of the fundamental properties of combustion. One way to gain this is through microgravity experiments, where the lack of buoyancy reduces flames to their most basic components ...

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.

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.

Abstract Unlike premixed flames, diffusion flames do not have a burning velocity. Interest therefore lies in their internal structure, in their rates of energy release, in rates of transport of fuel and oxidizer into the flame (burning rates), and in necessary conditions for their existence and extinction.
