Turbulent burning velocity, burned gas distribution, and associated flame surface definition
Combustion and Flame, 2003Abstract Experimental studies of premixed, turbulent, gaseous explosion flames in a fan-stirred bomb are reported. The turbulence was uniform and isotropic, while changes in the rms turbulent velocity were achieved by changes in the speed of the fans. Central spark ignitions created mean spherical flame propagation.

Turbulent premixed combustion: Flamelet structure and its effect on turbulent burning velocities
Progress in Energy and Combustion Science, 2008Abstract This review paper addresses the following question: what is the structure of flamelets within premixed turbulent combustion and how does this structure affect the turbulent burning velocity? We also ask: how accurately can new models predict the flamelet structure as well as the values of turbulent burning velocity?

Turbulent burning velocity of methane–air–dust premixed flames
Combustion and Flame, 2018Abstract Investigation of turbulent burning velocity (ST) of methane–air–dust premixed flames with different dust types (coal, sand and sodium bicarbonate) and dust concentrations (λp = 0–75 g/m3) were conducted at three methane–air pre-mixture equivalence ratios (ϕg = 0.8, 1.0 and 1.2) and different turbulent intensities ( u rms ′ = 0 ...

Symposium (International) on Combustion, 1977
Measurements are reported of premixed hydrogen-air turbulent burning velocities, made by the double kernel method during explosions. Turbulence was created by four high speed fans within the explosion vessel. The method is described for calibrating the system, which is capable of giving high values of turbulent Reynolds numbers. The values obtained are

Lewis number effects on turbulent burning velocity
Symposium (International) on Combustion, 1985Experimental 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.

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 ...

Studies of the turbulent burning velocity
Proceedings of the Royal Society of London. Series A: Mathematical and Physical Sciences, 1990A laminar flamelet model of pre-mixed turbulent combustion is described in which a characteristic length scale L̂ y controls the flamelet surface-to-volume ratio. An analysis, based on the Bray-Moss-Libby model of turbulent combustion, leads to the conclusion that

Measurement of turbulent burning velocity for large turbulent Reynolds numbers
Symposium (International) on Combustion, 1975Turbulent burning velocities have been measured in an explosion vessel equipped with four fans driven by air turbines. This arrangement created a central region of uniform isotropic turbulence in which measurements were made of flame speed, turbulent burning velocity and gas velocity just ahead of the flame front.

Influence of local flame displacement velocity on turbulent burning velocity
Proceedings of the Combustion Institute, 2002In 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 ...
