摘要
总结了用于计算CO2超临界状态下换热和压降的关联式,与相关文献中的实验数据进行了比较,结果表明Pettersen修正的换热关联式和Yin修正的换热关联式偏差较小,Churchill的压降关联式偏差最小。
Presents common heat transfer and pressure drop correlations, and compares them with experimental data from literatures, The results indicate that Pettersen＇s and Yin＇s modifications of heat transfer correlations and Chuichill＇s pressure drop correlation have less deviation than the other correlations,
