Laminar burning velocity measurements of stabilized aluminum dust flames
The laminar burning velocity of a stabilized dust flame is experimentally investigated in the present work. The dust used was aluminum powder with an average particle diameter of approximately 5 microns. Dust flames, in comparison to gas flames, are thicker and brighter, may be influenced by …

Laminar burning velocity of hydrogen and flame structure of related fuels for detailed kinetic model validation
The laminar burning velocity and the flame structure are common targets for combustion studies aimed at detailed kinetic model development. In the present work, fuels relevant to hydrogen combustion were considered. The laminar burning velocity of rich and lean hydrogen flames was studied …

Mechanisms of turbulent flame propagation
… 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 driven by electric motors within the explosion vessel. This arrangement created a central region of uniform, isotropic turbulence …

Fundamental studies of premixed combustion
… propagation,originating at a point under both laminar and turbulent propagation. Schlieren cine photography has been employed to study laminar flame propagation, while planar mie scattering (PMS) has elucidated important aspects of turbulent flame propagation. Thrbulent flame curvature has also …

Turbulent flame development in a high-pressure combustion vessel
… this work was to extend the range of turbulent burning velocities presented in the literature by performing new measurements at elevated pressures over a range of turbulent velocities, u' (r. m. s. deviation from the mean velocity). The influence of equivalence ratio was investigated for a fixed …

Experimental and theoretical studies of combustion rates at high pressure
… and temperature. It focuses on measurements of laminar and turbulent burning velocities at high pressures and temperatures approaching those in engines, with emphasis on flame instabilities. To encourage the development of such instabilities, mixtures with negative Markstein numbers were …

A computational and experimental study of spark ignition engine combustion
… found to decelerate. A relationship between the burning velocity of an unconstrained flame and a flame approaching a wall was derived which agreed well with the experimental results. This relationship was incorporated into the engine simulation code and found to improve greatly the predictions of …

Reduced Kinetic Mechanisms For Premixedhydrogen-air-cf3br Flames
… the addition of CF3Br significantly reduced the burning velocity of premixed H2/Air flames by depleting the important radical species that are important to sustain chemical reactions. Extending this finding to understand the suppression of more complicated diffusion flames and unsteady three …

Simulation of Turbulent Flames at Conditions Related to IC Engines
… combustion systems. It is well accepted that the laminar burning velocity, SL, is an essential parameter to determine the fuel burn rate and consequently the power output and ef ciency of IC engines. Also, it is involved in almost all of the sophisticated turbulent combustion models for premixed …
