摘要
运用热力学理论,对设有A型独立液货舱的大型全冷式液化气船(VLGC)的液货、船体结构及海水和空气之间的热传递过程作了研究并对船体结构温度分布作了计算。计算中,除考虑传统的对流和传导之外,还考虑了热辐射以及船体结构加筋板架翼翅效应(fin effect)的影响,提高了计算精度。建立了热传递能量平衡方程,并通过迭代法进行求解,最终得出了船体结构温度场分布。
The thermal transmission process among the liquid cargoes, the hull structures, the seawater and the air for a very large gas carrier （VLGC） with type A separate liquid tanks is studied based on thermal dynamic theories; the hull structure temperature distribution is computed, taking into account not only the conventional convection and conduction, but also the heat radiation and the fin effect caused by the stiffened plate of the hull structure, in order to improve computation accuracy. The heat transfer energy balance equation is established and solved through iteration to finally obtain the hull structure temperature distribution.
