Self-similar propagation and turbulent burning velocity of CH4/H2/air expanding flames: Effect of Lewis number

, 2020
In this study we clarify the role of differential diffusion characterized by effective Lewis number, Leeff, on the self-similar accelerative propagation and the associated turbulent burning velocity of turbulent expanding flames.

The determination of laminar burning velocity

Progress in Energy and Combustion Science, 1980
The relevance of data on laminar burning velocities, both from their value to industry and related research areas, and for the validation of theoretical chemical kinetic models, is discussed, as are certain fundamental problems associated with the measurement of this intrinsic property.

Kinetic study of the effects of hydrogen blending to toluene reference fuel (TRF)/air mixtures on laminar burning velocity and flame structure

, 2020
Because of its high reactivity, rapid flame speed, and low ignition energy, hydrogen is an excellent additive in gasoline to improve the combustion performance and reduce pollutant formation. In this study, we conducted a numerical study of the effect of

On the burning velocity of stretched flames

Combustion and Flame, 1991
Abstract The term “burning velocity” is commonly defined as the velocity of the gas ahead of and relative to the flame. This definition is appropriate for a one-dimensional flow because the mass flow rate across the flame is constant. In more general circumstances, however, this definition becomes ambiguous because the mass flow rate varies with ...

Determination of the Velocity of Burning

Nature, 1952
IN a recent paper by Linnet and Conan1, it is pointed out that the Schlieren cone is better suited for determining the velocity of burning than the luminous flame cone and the shadow cone. The Schlieren cone lies closer to the centre, as has been demonstrated by Broeze2 and by others.

Experimental and numerical study on laminar burning velocity of gasoline and gasoline surrogates

Fuel, 2019
The outwardly propagating spherical flame method was used to measure the laminar burning velocity of a Chinese commercial gasoline and gasoline surrogates. Measurements were conducted at different equivalence ratios of 0.8 to 1.5, initial temperatures of

Burning velocities of CO flames

Combustion and Flame, 1997
Asymptotic and computational methods are employed to investigate premixed laminar burning velocities of planar adiabatic flames in ideal gas mixtures containing carbon monoxide, oxygen, an inert, and trace amounts of hydrogen-containing species. The chemical-kinetic steps that control the burning velocity are identified, and the dependence of the ...
