摘要
对LNG空温式气化器的单根翅片管进行模拟换热计算,计算时将翅片管分为单相液、两相以及单相气3区,得出了管外壁温度、管内流体温度以及管内流体表面传热系数沿管长的分布。
The heat transfer calculation of a single finned-tube in ambient air vaporizer is simulated. The single finned-tube is divided into 3 areas including single-phase fluid, two phases and singlephase gas. The distributions of external wall temperature, internal fluid temperature and the surface heat transfer coefficient of the internal fluid along the length are obtained.
