火焰在障碍物作用下的失稳变形与障碍物的形状、大小以及作用方式有关.本文对火焰以翻越、穿越和绕过等三种方式与不同形状的障碍物相互作用时,火焰的发展变化特性与规律进行了实验研究.本文利用高速阴影照相系统,清晰的记录了不同形状的障碍物以不同方式与火焰作用时,火焰的变形和湍流的猝发,对不同作用方式下,火焰的结构特征进行了分析、比较和讨论.

The instability and transmutation of flame which interact with obstacle is interrelated with obstacle,s shape,dimension and action mode.This paper does some experimental researching on transformative rule and characteristic of flame when flame pass over,pass through or pass around different shape obstacle.This paper use highspeed shadow calnera system to shoot the transmutation of flame and the turbulence which is suddenly produced.This paper also discusses,compare and analyze the structure of flame when flame interacts with obstacle by different mode.
