密闭管道内瓦斯爆炸火焰传播行为可视化研究
|
摘要
运用管道爆炸传播实验系统,配合高速摄像机及纹影仪系统,对密闭管道内瓦斯爆炸过程中的火焰传播行为进行了实验研究。通过研究得出了瓦斯爆炸点火起爆阶段、爆炸初期阶段、爆炸充分发展阶段爆炸火焰的结构特征和传播行为变化规律,研究为有效预防和控制瓦斯爆炸事故提供了重要的理论依据。
The propagation law of gas explosion in a pipe full of gas was studied by using pipeline explosion experiment system. The structure characteristics and propagation behavior of explosive flame in ignition and detonation stage,initial stage and full development stage of gas explosion were obtained,the conclusions provide an important theoretical basis for effective prevention and control of gas explosion accidents.
