  • Image series of a moving fire on linear motion were acquired by a high-speed video camera. Applying image processing technology and the fractal theory, the fractal structure characteristic of the diffusion flame of moving fires was studied. The results revealed that the diffusion flame of moving fires possesses fractal dimension characteristics and it increases with the velocity in the same acceleration. When the velocity of a moving fire reaches a certain value, the fractal dimension of the diffusion flame increases within a small range; under the condition of a large acceleration and velocity, its fractal dimension increase rapidly with the velocity, and can influence the wrinkle and distortion. There are certain differences between a moving fire and a static fire, which can be identified by comparing the fractal dimensions of them.
