摘要
综述了国际上对亚临界二氧化碳管内换热特征的研究。提供了多种公开发表的亚临界流体在管内流动的换热关联式 ,并将实验关联式的计算结果与文献中的实验数据进行对照 ,在此基础上对关联式的准确性进行了讨论 ,并推荐了不同工况下适用的关联式。
This paper gives a review of the heat transfer characteristics of subcritical carbon dioxide in-tube flow. Some published correlations for heat transfer coefficient during in-tube flow are collected. The accuracy of the correlations is discussed through comparing the calculation results with the experimental data. The applicable correlations in different conditions are recommended.
