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 ...

An Experimental Study on Properties of Local Burning Velocity for Hydrogen Added Hydrocarbon Premixed Turbulent Flames

ASME/JSME 2011 8th Thermal Engineering Joint Conference, 2011
This study is performed to investigate directly the local flame properties of turbulent propagating flames at the same weak turbulence condition (u′/SL0 = 1.4), in order to clarify basically the influence of the addition of hydrogen to methane or propane mixtures on its local burning velocity.

Local flame structure and turbulent burning velocity by joint PLIF imaging

Proceedings of the Combustion Institute, 2011
Abstract In this study, we have examined local flame structure by joint PLIF imaging, using simultaneous HCHO/OH-PLIF and orthogonal OH-PLIF measurements. By considering the degree of flame wrinkling, three-dimensional flame surface area is obtained from 2D images.

DNS Analysis on Local Burning Velocity and Flame Displacement Speed of Turbulent Premixed Flames With Different Density Ratio

ASME/JSME 2011 8th Thermal Engineering Joint Conference, 2011
To investigate the relationship between local burning velocity and flame displacement speed with different density ratio, a numerical analysis was performed using DNS databases of statistically steady and fully developed turbulent premixed flames. The local burning velocity based on fuel consumption rate is considered to be most appropriate as the ...

Direct measurement of local instantaneous laminar burning velocity by a new PIV algorithm

Experiments in Fluids, 2010
This paper presents a new experimental approach using PIV technique to measure the local instantaneous laminar burning velocity of a stretched premixed flame. Up to now, from experimental techniques, this physical property was only accessible in average and the instantaneous interactions of flame with flow structures, mixture variations and walls could
