Soot formation and radiation in turbulent jet diffusion flames under normal and reduced gravity conditions [PDF]

Most practical combustion processes, as well as fires and explosions, exhibit some characteristics of turbulent diffusion flames. For hydrocarbon fuels, the presence of soot particles significantly increases the level of radiative heat transfer from ...

Numerical investigation of the Soret effect on burning velocity of lean hydrogen flame

Journal of Thermal Science and Technology
2D numerical simulations of a wrinkled lean hydrogen (H2)-air premixed flame are performed with and without considering the Soret effect to investigate the Soret effect on flame propagation.

Fundamental approach to laminar flame propagation [PDF]

, 1954
The complete system of equations for a theory of laminar flame equations is presented, taking into account both heat conduction and diffusion, for the case of an arbitrary number of simultaneous reactions.

Blending effect between the natural gas and the liquefied petroleum gas using multiple co- and cross-flow jets on NOx emissions

Ain Shams Engineering Journal, 2019
A burner comprising multiple co- and cross-flow jets was developed to address the effect of blending the natural gas (NG) with the liquefied petroleum gas (LPG) on the NOx emissions from laminar/turbulent diffusion and triple flames in the normal and ...

Flame spread in laminar mixing layers: the triple flame [PDF]

, 1993
In the present paper we investígate flame spread in laminar mixing layers both experimentally and numerically. First, a burner has been designed and built such that stationary triple ñames can be stabilised in a coflowing stream with well defined linear ...

Analysis of opposed jet hydrogen-air counter flow diffusion flame [PDF]

A computational simulation of the opposed-jet diffusion flame is performed to study its structure and extinction limits. The present analysis concentrates on the nitrogen-diluted hydrogen-air diffusion flame, which provides the basic information for many
