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.

Flame speed in diffusion dominated premixed flames
Combustion Theory and Modelling, 2022 Development of a premixed flame theory that includes the effects of flame stretch and curvature has been at the forefront of combustion research. Diffusion dominated flames such as highly curved flame balls present a challenging flame structure that has not been included in current flame stretch theory so far.

LIFTED LAMINAR JET DIFFUSION FLAMES [PDF]
Combustion Science and Technology, 2005 This paper addresses the numerical description of lifted flames in axisymmetric laminar coflow jets. The analysis considers moderately large values of the Reynolds number, when the boundary-layer approximation can be used to describe the slender mixing region that extends between the jet exit and the flame, providing the profiles of velocity and ...

The Coherent Flame Model for Turbulent Chemical Reactions [PDF]
, 1977 A description of the turbulent diffusion flame is proposed in which the flame structure is composed of a distribution of laminar diffusion flame elements, whose thickness is small in comparison with the large eddies.

Defects Dynamic in Photo‐Excited CeO2 and their Influence on CO2 Photoreduction
Advanced Functional Materials, EarlyView.X‐ray photoelectron spectroscopy study under light excitation is presented to track the defect dynamic (Ce4+ to Ce3+) in CeO2. Surface enhanced Raman spectroscopy confirmed the key role of Ce3+ states in controlling charge and energy transfer across the CeO2‐dye molecule interface.

Opposed flow diffusion flame extensions [PDF]
Symposium (International) on Combustion, 1981 The Opposed Flow Diffusion Flame (OFDF) apparatus has been used for estimating the thermochemical properties of materials related to fire safety and for diffusion flame structure studies. Here the extension of the flame beyond the pyrolyzing fuel surface and the excess pyrolyzate are predicted.
