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。
A key factor of gas explosion is ignition energy. Therefore, a gas explosion experimental system with different ignition energies is constructed. The visualization of gas explosion by using high-speed cameras and other equipment provides a new reliable experimental platform for gas explosion. The flame characteristics and flame propagation velocity of gas explosion under two kinds of long-span energy are systematically analyzed. The flame propagation rules of gas explosion under different ignition energies are obtained.
