Summarization and Evaluation of Supercritical Heat Transfer Correlations

CNNC Key Laboratory on Nuclear Reactor Thermal Hydraulics Technology, Nuclear Power Institute of China, Chengdu, 610041, China

摘要: 在超临界条件下流体升温过程中不会出现相变,所以现有的超临界传热关系式基本都是参考亚临界条件下的单相传热关系式再添加相应的修正项得到。对现有的超临界传热关系式进行分类整理,介绍各类计算方法的特点并用实验数据对各类计算方法进行了评估,结果发现Bishop和Jackson关系式的计算结果与实验数据偏差相对较小,这类关系式的计算精度稍高。

Abstract: There is no phase change with the increasing of temperature under supercritical pressure.Most of the existing supercritical heat transfer correlations have the general form of single phase heat transfer cor-relations at sub-critical conditions with some modifications.The supercritical heat transfer correlations are summarized in this paper.The comparison of the correlations with the experiment data shows that Bishop and Jackson correlation fit well with the experiment data,and the correlation of this type is more accuracy than others.
