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.

Effect of hydrogen addition on laminar burning velocity of CH4/DME mixtures by heat flux method and kinetic modeling

Fuel, 2018
Laminar burning velocities were measured by the heat flux method for premixed methane dimethyl-ether mixtures (CH4/DME) with air, at various mixture fractions from 100% CH4 to 100% DME with hydrogen addition of 0%, 20% and 40%.

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 ...

Data consistency of the burning velocity measurements using the heat flux method: Hydrogen flames

Combustion and Flame, 2018
Consistent datasets of experiments are highly important both for validation and optimization of kinetic mechanisms. An analysis of the data consistency of all available burning velocity measurements of hydrogen flames using the heat flux method at ...
