摘　　要：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。The available experimental data of heat transfer for water and the empirical correlations which are used to predict heat transfer at supercritical pressure in vertical upward tubes are extensively collected.The calculated values of these experimental correlations are compared with the experimental value of the heat transfer deterioration,errors and accuracy analyses for these correlations arrived are presented.The heat transfer experimental data in vertical upward tubes are fitted to get a new heat transfer correlation.An error analysis for the new correlation is presented which works well with heat transfer deterioration.
