Developing New Heat-Transfer Correlation for SuperCritical-Water Flow in Vertical Bare Tubes

Abstract: This paper presents an analysis of heat transfer in water at supercritical conditions in bare vertical tubes. A large dataset within conditions similar to those of SuperCritical Water-cooled nuclear Reactors (SCWRs) was obtained from the Institute for Physics and Power Engineering (Obninsk, Russia). This dataset was compared to existing heat-transfer correlations from the open literature. This comparison is an extension to the previous studies done with this dataset. Previous studies have shown that existing c… Show more

“…The accuracies of the Gupta et al (2010) and Swenson et al (1965) correlations are very close, having the MAD less than 18.5% and predicting about 80% of the experimental data in the deteriorated heat transfer regime within ±20%. The Xu et al (2005) correlation has the smallest RMSD (31.3%) and SD (31.1%) and predicts 66.2% of the deteriorated data within ±20%.…”

“…The McAdams (1942) correlation has the smallest MAD (10.3%), RMSD (14.2%), and SD (11.1%), predicting 82.8% of the experimental data in the enhanced heat transfer regime within ±20% and 94.4% within ±30%. (4) For the deteriorated heat transfer regime, the correlations of Gupta et al (2010), Swenson et al (1965), and Xu et al (2005) are the most promising ones. The Gupta et al (2010) correlation has the smallest MAD of 18.1%, predicting 77.6% of the experimental data in the deteriorated heat transfer regime within ±20%, and 86.8% within ±30%.…”

“…7 and 8). New correlations developed for SCW - Mokry et al (2009b and Gupta et al (2011), which show good results for SCW data, cannot be directly applied to SCCO 2 , as thermophysical properties of these two fluids differ significantly (refer to discussion in Section 2). Therefore, empirical heat-transfer correlations based on bare-tube SCCO 2 data and its latest thermophysical properties should be developed.…”
