摘要
通过高速纹影图像从细观角度详细研究了瓦斯爆燃火焰内部流场的细微结构。实验表明 :火焰内部流场具有明显的分形特征 ,且不同传播条件下分形维数不同。分形维数的大小对火焰内部结构与火焰传播有很大影响 。
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.
