On the Correlation of Turbulent Burning Velocities

Combustion Science and Technology, 1980
Abstract A new formulation of the spectral interpretation of turbulent burning velocities is proposed. The correlation formula based on this interpretation is tested against existing experimental data on turbulent burning ...

Influence of local flame displacement velocity on turbulent burning velocity

Proceedings of the Combustion Institute, 2002
In our previous works, the mean local burning velocity turned out to be changed from the originallaminar burning velocity due to the preferential diffusion effect, and it was found to be an important factor dominating the turbulent burning velocity. The present study investigates directly the local flame propagation properties of methane, propane, and ...

Effect of pressure on turbulent burning velocity

Combustion and Flame, 1958
Abstract Turbulent burning velocities were measured for three fueloxidant systems (propaneair, hydrogenair, and propane50 per cent oxygen50 per cent nitrogen) over a range of pressures at nearly constant Reynolds number. At constant Reynolds number, the pressure exponent for turbulent burning velocity was consistently about 0·3 greater in ...

Turbulent Burning Velocity of Lean Hydrogen Mixtures

SAE Technical Paper Series, 2003
<div class="section abstract"><div class="htmlview paragraph">The present study is performed to examine experimentally the turbulent burning velocity characteristics of lean hydrogen mixtures with attention to the local burning velocity. The special mixtures, having nearly the same laminar burning velocity with different equivalence ratios ...

Is turbulent burning velocity a meaningful parameter?

Combustion, Explosion and Shock Waves, 1993
The concept of turbulent burning velocity arises from an analogy with that of the laminar burning velocity. Experimental measurement or theoretical computation of the latter must take account of the effects of flame stretch. This is also necessary for turbulent flames, and when flame propagation originates at a point source, there is a temporal ...

Structure and burning velocity of turbulent premixed flames

Combustion and Flame, 1968
Abstract Annular turbulent premixed flames have been stabilized by means of an ‘opposed jet burner’. Determinations of the mean gas flow velocity, the intensity of turbulence, the Eulerian scale and the microscale have been made in the flame stabilization region; the thickness of the flame has been estimated from photographic pictures.

Modification of the turbulent burning velocity by gas expansion

Proceedings of the Combustion Institute, 2000
Premixed turbulent combustion in the corrugated flamelets regime has been addressed by modeling of a G-equation containing a gas-expansion term, the form of which was derived by generalizing results of Sivashinsky along lines initiated by Frankel. Previous analyses by the first author of the mean, variance, and two-point correlation spectrum of G, as ...

Lewis number effects on turbulent burning velocity

Symposium (International) on Combustion, 1985
Experimental values of turbulent burning velocities for propane, hydrogen and iso-octane mixtures with air are reported under conditions of high turbulence and high turbulent Reynolds number. The measurements were made by the double kernel method during explosions in a fan-stirred bomb, with four fans, capable of speeds of up to 10,000 rpm.
