摘要
考虑火灾环境下液化气球罐受热辐射的影响 ,根据热响应模型 ,通过有限元分析 ,研究环境温度达到高温时液化气球罐的瞬态热响应的行为 ,得到了球罐以及内部介质的温度场 ,研究结果与所建立的物理模型相吻合。在此基础上 。
In the present paper, effect of thermal radiation on LPG spherical tanks in fire environment was taken into account. According to thermal response model, transient thermal response of LPG spherical tanks at high temperature was analyzed by finite element method, the temperature distribution of spherical tank and inner medium was obtained. The research results were coincided with established physical model. Based on this, effect of filling and heat flux on thermal response of LPG tanks was further analyzed.
