以乙炔 -空气为介质实验研究了平板形障碍物对可燃气云爆燃强度的影响 ,运用曲线拟合方法获得了弱点火条件下气云爆燃时平板形障碍物上的压力分布与气云初始半径、平板离开爆源中心的距离之间的关系式 ,为气云爆炸的缩放研究提供了基础 .讨论了平板形障碍物对气云爆燃强度的影响 .
The effect of plate-shaped obstacle on the deflagration intensity of combustible gas cloud was studied by using acetylene-air as a medium. The pressure distribution on the flat-shaped obstacle with deflagration of the cloud gas and the initial radius of cloud , The relationship between the distance of flat plate from the explosion source center, which provides a basis for the scaling study of gas cloud explosion.The effect of flat-shaped obstacles on the deflagration intensity of gas cloud is discussed.
