Dependence of turbulent burning velocity on turbulent reynolds number and ratio of flaminar burning velocity to R.M.S. turbulent velocity

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

Turbulent burning velocity of stoichiometric syngas flames with different hydrogen volumetric fractions upon constant-volume method with multi-zone model

, 2020
Syngas has been widely concerned and tested in various thermo-power devices as one promising alternative fuel. However, little is known about the turbulent combustion characteristics, especially on outwardly propagating turbulent syngas/air premixed ...

Temperature effect on turbulent burning velocity of lean premixed hydrogen/air flames

The Physics of Fluids
Hydrogen has drawn great attention in recent years as a carbon-free fuel. The turbulent burning velocity (ST) is an important parameter for the design and modeling of hydrogen-fueled engines given the high propagation speed of hydrogen flames.

Measurement of turbulent burning velocity for large turbulent Reynolds numbers

Symposium (International) on Combustion, 1975
Turbulent 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.

Studies of the turbulent burning velocity

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