Laminar burning velocity of hydrogen and carbon-monoxide enriched natural gas (HyCONG): An experimental and artificial neural network study

Fuel, 2019
The laminar burning velocity of H2 and CO enriched natural gas (HyCONG) mixtures measured through spherically expanding flames method under three different fuel-air equivalence ratios (0.6, 0.8, and 1.0) at room temperature and atmospheric pressure ...

The influence of turbulence on the burning velocity of premixed CH4-H2 flames with different laminar burning velocities

Symposium (International) on Combustion, 1989
The influence of the turbulence on the turbulent burning velocity ST of a premixed flame, characterized by a flat flame front stabilized in a stagnation flow was investigated using a two component Laser-Doppler-velocimetry (LDV) technique. The use of different CH4-H2 combustion mixtures enabled the laminar burning velocity SL: to be varied between 0 ...

Burning velocity measurements of nitrogen-containing compounds

Journal of Hazardous Materials, 2008
Burning velocity measurements of nitrogen-containing compounds, i.e., ammonia (NH3), methylamine (CH3NH2), ethylamine (C2H5NH2), and propylamine (C3H7NH2), were carried out to assess the flammability of potential natural refrigerants. The spherical-vessel (SV) method was used to measure the burning velocity over a wide range of sample and air ...

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%.

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 ...

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 ...
