摘要
在单元法基础上，分析了封闭薄壳结构的物体在海天环境中的传热学过程及各种因素的影响；对物体进行了三维划分，根据面元主要热物性参数进行了分类，并引入了两类新的温度修正公式．根据改进后的单元法进行了数值计算。
Based on the SEM (Single Element Method), the heat transfer process of object with enclosure shell structure in the ocean was investigated. The 3 D object was divided into different elements which were classified according to their thermal characteristics. Two temperature correction formulas which were very important to the simulated infrared thermogram were developed for the first time. The 3 D temperature distribution of the object was obtained through simple numerical calculation, and the simulated infrared thermogram was also given.
