以船舶隔热结构传热系数为研究对象，首先对数值模拟方法进行实验对比验证，随后对船舶隔热结构传热系数进行数值模拟，并进行对比分析。结果表明，相关标准中船舶隔热结构传热系数取值过于保守；船舶隔热结构空气层厚度和温差对船舶隔热结构传热系数影响较小，其值随空气层厚度增大而减小；当高、低温壁面一定时，其值随壁面温差的增大而增大，相同组成的船舶隔热结构用于舱壁时的传热系数略大于用于甲板时，以往文献的研究方法和结论存在不足之处，本文方法可以得到更准确的值。在实际设计中，可对船舶隔热结构进行数值模拟以得到更精确的传热系数和负荷计算结果，本文结果对船舶隔热结构传热系数的取值和数值模拟提供依据。
The paper takes the heat transfer coefficient of ship thermal insulation structure as the research object, firstly, the numerical simulation method was verified by experimental comparison, and then the heat transfer coefficient of ship thermal insulation structure was simulated numerically and analyzed comparatively. The results show that the value of heat transfer coefficient of ship thermal insulation structure in the relevant standards is too conservative; the thickness of the air layer of ship thermal insulation structure and the temperature difference have less influence on the heat transfer coefficient of ship thermal insulation structure, and its value decreases with the increase of the thickness of the air layer; the value increases with the increase of the temperature difference of the wall when the wall surface of the high and low temperatures is certain; the heat transfer coefficient of the same composition of the ship thermal insulation structure used for the bulkheads is slightly larger than that used for the deck, and the research methods and conclusions of the previous literature are insufficient. The research methods and conclusions of the previous literature are insufficient, and the method used in the thesis can get more accurate values. In the actual design, numerical simulation can be carried out to get more accurate heat transfer coefficient and load calculation results for ship thermal insulation structure. The results of the paper provide a basis for the value of heat transfer coefficient and numerical simulation of ship thermal insulation structure.
