| 摘 要： | 瓦斯爆炸的一个关键因素是点火能量,因此,构建了不同点火能量的瓦斯爆炸实验系统,采用高速摄影仪等设备对瓦斯爆炸进行了可视化研究,为瓦斯爆炸提供了新的可靠实验平台。并针对2种大跨度能量作用下瓦斯爆炸火焰特征与火焰传播速度进行了系统分析,得出了不同点火能量作用下瓦斯爆炸火焰传播规律。 |
| 关 键 词： | 点火能 瓦斯爆炸 火焰传播 管道 特征 |

| Abstract: | A key factor of gas explosion is ignition energy,therefore,by setting up gas explosion experimental system in different ignition energy,and visual studying of gas explosion used by high-speed photographic apparatus and other equipment,a new and reliable experimental platform of gas explosion is built.It is analyzed systematically that flame characteristics and flame propagation speed of gas explosion in two kind of large span energy,and it is come that flame propagation law of gas explosion in different ign... |
| Keywords: | ignition energy gas explosion flame propagation duct characteristics |
