在目前的工作中的数据集的实验点和传热的相关性文献中的液体金属充分发展，强制对流传热管进行了审查和批判性分析。来自21个不同来源的1,100多个数据点被认为是恒定的热通量，涵盖了广泛的操作条件（速度，热通量，直径等）。在评价的15个关联式中，推荐了4个适用于强制湍流对流的关联式：一个包含所有数据点，另外3个分别与碱金属、铅合金和汞有关。此外，一个新的相关性已被推导出作为一个最佳的拟合有限数量的可用数据点恒定的壁温，而另一种评估方法也描述了这种边界条件。
Within the present work the dataset of experimental points and the heat transfer correlations available in literature for liquid-metal fully-developed, forced-convective heat transfer in pipes are reviewed and critically analyzed. Over 1,100 data points from 21 different sources are considered for constant heat flux, covering a wide range of operating conditions (velocity, heat flux, diameter, among others). Among 15 evaluated correlations, four appropriate ones are recommended for forced turbulent convection: one covering all the data points and the other three respectively related to alkali liquid metals, lead alloys and mercury. Moreover, a new correlation has been derived as a best fit of the limited number of available data points for constant wall temperature, while an alternative evaluation method is also described for this boundary condition.
