摘要
借助CFD模拟软件及其并行技术,以圆柱体钢结构件为研究对象,应用整场离散、整场求解的数值解法,初步探讨了火焰流场与结构热响应的耦合模拟方法,开展了静风及有风条件下3m直径油池火灾环境下包装容器的热响应特性模拟,得到了水平放置的包装容器表面温度及热流响应的空间分布特性,研究结果可为含危险品结构的热-力耦合响应模拟提供载荷边界条件,为含危险品结构的热安全性评估提供技术支撑。
Coupling simulation method between flame flux and thermal response of structure was discussed u- sing computation fluid dynamics （CFD） simulation software and parallel technique, with cylinder steel structure as object, using numerical method of discrete and derivation in all domain. Thermal response of package in three-meter diameter pool fire under stagnant air and cross-wind was simulated. The regularity of temperature and heat flow response on horizontal setting container in stagnant air and cross-wind was obtained. The results can provide thermal-mechanics coupling simulation of the structure including dangerous goods with load bounda- ry condition, thereby providing a theoretical reference for security assessment of the structure including dangerous goods.
