Experimental study on the fractal characteristic of methane explosion flame

摘要：

In this paper flame microstructures and propagation characteristic of methane explosion are studied by high speed schlieren photography technique. By experiment it shows that flame front surface and inner flow field of methane explosion has distinctly fractal characteristic, the effect of the wrinkle of flame front surface and inner reactants on flame propagation can be directly reflect by fractal dimensions. Fractal dimension has a direct relation to flame structure and flame propagation characteristics, and it is the important parameter to scale the flame propagation velocity and flame temperature.
