水平管道中瓦斯爆炸火焰传播速度测量
Propagation velocity measurement for flame of gas explosion in horizontal tube
摘要
Abstract
In coal industry, gas explosion accidents emerge constantly, causing enormous casualties and poorer material property. In the course of studying gas exploding mechanism, the propagation velocity of the flame wave front is one of the most important factors. A set of flame velocity measuring system was designed according to the horizontal pipelined experimental facility of North University of China to study the effects of the quantity and blockage ratio of the circle ring obstacle on the flame propagation velocity in the inclosed tube.The research results show that the obstacle has obviously accelerating effect on the flame wave of gas explosion. With the increase of quantity and blockage ratio of the obstacle, the flame accelerating effect becomes more obvious and the flame accelerating persistence is intenser, of which the effect of the quantity of the obstacle on the flame accelerating persistence is larger, but the effect of the blockage ratio of the obstacle on the flame accelerating persistence is not obvious.关键词
