In this paper the microstructure of flame in methane/air explosion has been studied indetail by using high speed schlieren photographs. The experiments shows that flame inner flow field has distinctly fractal characteristics, and the fractal dimensions are different under different experimental conditions. The fractal dimensions of flame inner flow fields have remarkable effects on flame inner microstructure and flame acceleration and also are effective parameters that can reflect flame velocity.
