平板布置对气云爆炸场影响

Effect of plate layout on pressure field of flammable gas cloud explosion

以乙炔 -空气气云为可燃介质 ,进行了半径为 5 0 cm半球形气云爆炸实验。气云外布置了平板形障碍物 ,平板距球心的距离分别为 5 7cm和 1 0 0 cm,平板的布置分为单板、双板垂直、双板平行、3板槽形和 4板口形放置 5种方式。结果表明 ,平板对气云爆炸威力有加强作用 ,对气云的约束越大 。

The explosion experiments were conducted of C 2H 2 air semi spherical clouds with a radius of 50 cm. Outside the clouds existed plates that were 57 cm and 100 cm from ignition point respectively. There were 5 types of layouts that were single plates, double parallel plates on both sides of the cloud, double plates on two perpendicular sides of the cloud, three plates on three sides around the cloud and four plates on four sides around the cloud. The experimental results show that the plates in explosion field enhance the explosion power and the larger the binding force on gas cloud is, the higher the explosion pressure is.
