摘要
针对液化石油气储罐受热压力上升而导致爆炸的问题,建立了液化气均相模型和分层模型,并对这两个模型的升压过程进行了比较。计算结果分析表明,液化石油气中分层区的存在加快了储罐的升压过程,另外,还分析了热流密度等对液化石油气储罐升压过程的影响。
In this paper,the homogeneous model and thermal stratification model are set up and they are used to model the pressurization in LPG vessel heated by fire. The analytical results show that the process of pres-surization is speeded up when stratification region exists. And the influence of other factors on pressurization is analyzed.
