Study of preferential diffusion effects in a hydrogen premixed flame [PDF]
, 2023 Transport phenomena give structure to flames, thus, being a key mechanism of combustion reactions. Molecular hydrogen (H2) combustion is characterized by strong preferential diffusion effects due to differences between the diffusion coefficients of each species involved in the reaction.

Experimental Study on Local Flame Properties of Hydrogen Added Hydrocarbon Premixed Turbulent Flames
Journal of Thermal Science and Technology, 2009 This experimental study is performed to investigate directly the local flame properties of turbulent propagating flames at the same weak turbulence condition (u'/SL0=1.4), in order to clarify basically the influence of the addition of hydrogen to ...

Visualization of Influence of Preferential Diffusion in Jets.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1997 Preferential diffusion in nonreacting jets was visualized by a Rayleigh scattering method. The jets initially consist of a mixture of CO2 and He with volume fractions 39.9 and 60.1, the effective Rayleigh scattering cross-section of which is the same as that of air.

Effects and Evaluation of Preferential Diffusion in Flames.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1996 Numerical computations are carried out for laminar jet diffusion flames taking detailed chemical kinetics and multicomponent diffusion into consideration. Attention is paid to the effects of the preferential diffusion of heat and species. The results obtained are as follows.(l) The computations predict well the experimental profiles of temperature ...
