管道分叉对瓦斯爆炸火焰传播速度影响的研究

Experimental Research of Tube Furcation's Influence on Flame Transmission Speed in Gas Explosion

在实验的基础上,研究了管道分叉对瓦斯爆炸过程中火焰传播规律的重要影响。管道分叉时,产生附加湍流,使瓦斯爆炸过程中火焰的传播速度迅速提高。研究结果对指导现场如何防治瓦斯爆炸,减轻瓦斯爆炸的威力具有重要作用。

This paper studies the influence on the flame transmission law in gas explosion of tube furcation. When the tube is biforked,the additional turbulent flow will be produced,which will improve the flame transmission speed in gas explosion. The research results will play an important role in the guidance of preventing gas explosion from occurring and in reducing the explosion power onproduction field.
