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

Burning velocity of methane-air flames

Combustion and Flame, 1969
Abstract Burning velocity measurements using stationary flames have been refined to give results with a mean error as low as ± 1 per cent. The method employs nozzle burners and a single pass schlieren system. Precautions have been taken to minimize errors at each stage of the experiments and calculations. The influence of burner design and the use of

Laminar burning velocities of various silanes

Journal of Loss Prevention in the Process Industries, 2015
Abstract In the present investigation, laminar burning velocities (LBVs) were measured for several different silane fuels (i.e., trichlorosilane, trimethylchlorosilane, methyldichlorosilane, dimethylchlorosilane, and tetramethylsilane) in order to evaluate their potential for vapour cloud explosions (VCEs).

Burning velocities of fluorocarbon-oxygen mixtures

Combustion and Flame, 1970
The burning velocities of mixtures of perfluoropropene (C 3 F 6 ), perfluorocyclobutene (c-C 4 F 6 ), and perfluorocyclobutane (c-C 4 F 6 ) with oxygen at atmospheric pressure are reported. The peak burning velocity of fluorocarbon-oxygen mixtures cannot be correlated with the peak calculated adiabatic flame temperature, but it is shown that the peak ...

Burning velocities of hydrogen-air mixtures

Combustion and Flame, 1993
Abstract Laminar and turbulent burning velocities of hydrogen-air mixtures have been determined in a 17-L vessel using the double-kernel technique for a range of hydrogen concentrations between 9% and 70% by volume. Over the range of mixtures investigated, simple empirical correlations yield laminar burning velocities that are in good agreement with ...

Burning velocity measurement by bomb method

Combustion and Flame, 1974
The bomb method of measuring burning velocity of a combustible mixture has important advantages over the conventional burner methods. The spatial flame velocity is determined by using a simple pulse circuit and ionization probes, and the burning velocity is computed from this data. The method is suitable for a wide range of pressures and mixture ratios.

Studies of the turbulent burning velocity

Proceedings of the Royal Society of London. Series A: Mathematical and Physical Sciences, 1990
A 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

Flame modelling and burning velocity measurement

Symposium (International) on Combustion, 1982
Strictly, the term “burning velocity” is only meaningful in relation to planar flame frontsin one-dimensional flow systems. On the other hand, burning velocity measurements are obtained from flames which are frequently curved, and in systems where the flow diverges to a greater or lesser extent on approach to the reaction zone.

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 ...
