本文在较宽广的工况范围内收集、整理了垂直上升光管内超临界压力水的对流传热实验数据(包括传热恶化实验数据)以及超临界压力水传热的计算关联式。将收集到的传热关联式与传热恶化实验数据进行比较,进行误差分析。对传热关联式的形式分析后,对垂直上升管中传热实验数据进行拟合得到一个新的传热关联式并对其进行评价,效果较好。

This paper collects and computes the convective heat transfer experimental data of supercritical pressure water (including experimental data of heat transfer deterioration) and the correlation of supercritical pressure water heat transfer in a wide range of working conditions. The collected heat transfer correlation and heat transfer deterioration of experimental data were compared for error analysis. After the formal analysis of the correlation of heat transfer, fitting a new heat transfer correlation to the experiment data of heat transfer in the vertical riser and obtaining a good result.
