Diffusion flames and diffusion flame-streets in three dimensional micro-channels
Combustion and Flame, 2017Abstract Experiments of non-premixed combustion in micro-channels have exhibited different modes of burning. Typically, a diffusion flame is established along or near the axis of a channel spanning the entire mixing layer. It separates a region of fuel and no oxidiser from a region with only oxidiser. Often, however, a periodic sequence of extinction

Flame height measurement of laminar inverse diffusion flames [PDF]
Combustion and Flame, 2006 Flame heights of co-flowing cylindrical ethylene-air and methane-air laminar inverse diffusion flames were measured. The luminous flame height was found to be greater than the height of the reaction zone determined by planar laser-induced fluorescence (PLIF) of hydroxyl radicals (OH) because of luminous soot above the reaction zone.

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 ...

Flame holes and flame disks on the surface of a diffusion flame
Journal of Fluid Mechanics, 2004Flame holes and flame disks in a laminar axisymmetric counterflow configuration are numerically investigated for unity Lewis number, with the strain rate as the control parameter. The temporal evolution of the topological structure of flame holes and flame disks is described in detail for different representative strain rates.
