摘要
埋地成品油管道泄漏后,成品油如果渗出地面或聚集到地面低洼处,在成品油强挥发性下会迅速产生大量的油蒸汽,油蒸汽又会在风速作用下快速向四周蔓延,无论发生燃烧还是爆炸都会给管道运营企业、沿线居民带来巨大的生命和财产损失。通过建立输油管道泄漏扩散过程的物理模型,利用COMSOL软件进行二维数值模拟,分析成品油在大气中泄漏不同时间内最大横向扩散宽度、最大纵向扩散深度的变化规律,有助于分析事故后果影响范围,提高事故的应急控制能力。
The product oil will go to the surface or accumulate at the pitting area after the buried pipes leaking.Because product oil has a strong volatility, a big amount of oil steam can be formed and it spreads quickly with the effect of wind. It will lead to severe life lose and wealth lose to the pipeline operating companies or the related surrounding citizen, no matter it burns or explodes. Based on establishing physical models for leaking process of piping, with the two-dimensional data stimulation by COMSOL, the variation rule on product oil leaking in the air horizontally and vertically with different time is analyzed. The research would be significant for analyzing the effects of accidents and improving accident aid capability.
