摘要
在实际生产过程中,有很多情况能使气体燃料与空气混合,达到可燃浓度,此时若有点火源存在,就可能酿成燃烧、爆炸灾害,造成严重的财产损失和人员伤亡。选取甲烷作为研究对象,选用空气作为氧化性气体,对其进行数值模拟。获得了不同时刻爆燃的压力场、温度场、密度场的变化数据,为工程上防爆、抑爆、泄爆提供了理论基础和数据。
In the actual production process, it is easy to cause the gaseous fuel and the air mixing, and to achieve the inflammable density in many situations. If there is a little ignition source existed, it possibly leads to combustion, explosion hazards, which could cause serious property damage and human casualties. In this paper, the methane is taken as the object of the study; the air is selected as the oxidized gas. The numerical simulation to the mixture .has been carried out. The conflagration pressure field, the temperature field and the density field changing data in the different time have been obtained. The theoretical basis and the data for guarding against explosions, the explosion suppression for project have been provided.
