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 ...

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 ...

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 ...

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 ...

On the Correlation of Turbulent Burning Velocities

Combustion Science and Technology, 1980
Abstract A new formulation of the spectral interpretation of turbulent burning velocities is proposed. The correlation formula based on this interpretation is tested against existing experimental data on turbulent burning ...

Effect of Addition of Radicals on Burning Velocity

AIAA Journal, 2001
by Yeo et al. in the potential  ow over a single-layer viscoelastic wall. On the other hand, no cusp points have been found at the ®i contours for an undamped plate (dD 0). All of the ®i 6D 0 contours are discontinuousin upper-half plane; ! roots jump to the opposite side of the real axis before the contours form cusps. It, therefore, indicates that a

ON THE BURNING VELOCITY OF ATOMIZED FUEL

1962
Abstract : ON THE BASIS OF A NUMBER OF ASSUMPTIONS, AN ATTEMPT HAS BEEN MADE TO EVALUATE THE VALUES OF THE BURNING-VELOCITY CONSTANT COMPLICATED CONDITIONS PARTICULARLY FOR THE BURNING OF AN ENSEMBLE OF DROPS OF DIFFERENT DIMENSIONS IN A HIGH VELOCITY TURBULENT FLOW. (Author)
