| 摘 要： | 国内针对薄膜型LNG船的温度场分析中,纵向构件及空间的计算结果已能保证一定的计算精度,但对于横向隔离舱通常未予关注,或计算结果与某薄膜型围护系统设备商（如GTT）的差异较大。文中针对薄膜型LNG船的横向隔离舱进行温度场分析,提出一种简化的计算方法,并研究归纳了一组自然对流系数的简化公式。通过和GTT提供的结果对比,证明该方法可行,且能保证一定的计算精度。

| Abstract: | For the temperature field analysis of membrane tank LNG carriers,calculation accuracy of longitudinal structure and space can be ensured.However,the researches of the transverse cofferdam have not been seriously considered,the results differ a lot from the equipment manufacture（e.g.GTT） of the membrane cofferdam system.This paper performs the temperature field analysis of the transverse cofferdam of the membrane tank LNG caries,puts forward a simplified calculation method,and deduces a set of simplified functions of natural convection coefficient.By comparison with the results provided by GTT,the proposed method is testified to be feasible to ensure the sufficient calculation accuracy. |
