Journal ArticleDOI
TL;DR: In this article, a large amount of experimental data were obtained from the experiments supplementing the extensive database previously compiled for fossil fuel-fired power plants, and prediction methods for heat-transfer coefficient were developed from various databases.

Journal ArticleDOI
TL;DR: In this paper, a mechanistic model was developed for predicting critical heat flux (CHF) in subchannels of a bundle, which is based on the bubble crowding phenomena and takes into the account of effects of velocity distributions, turbulent mixing intensity and Prandtl mixing length on CHF in sub-channels within the bundle.

Journal ArticleDOI
TL;DR: In this article, 20 correlations were assessed against the experimental data obtained in a 2 × 2 rod bundle and the results indicated that the correlation proposed by Chen-Fang is the best with an average error of −0.44% and a standard deviation of 6.4%.

Journal ArticleDOI
TL;DR: In this article, the effectiveness of heat transfer from the fuel rods to the moderator in a Canadian, pressure-tube type, Super-Critical Water-cooled Reactor (SCWR) has been assessed for the postulated loss-of-coolant accident (LOCA) coupled with the total loss of emergency core cooling (LOECC) event using the safety analysis code “SCTRAN”.

Journal ArticleDOI
TL;DR: In this article, the authors presented a general supercritical heat transfer (SHT) correlation for advanced power cycles, where the pseud-boiling assumption is introduced to deal with SHT.

Journal ArticleDOI
TL;DR: In this paper, the characteristics of abnormal heat transfer of supercritical carbon dioxide (SCO2) at various ranges of mass flow rate in heated vertical-flow tube were investigated, and a new correlation was developed based on the heat transfer data more than 2800 which sets from 10 independent experiments.

Journal ArticleDOI
TL;DR: In this paper, a new heat transfer correlation was developed for S-CO2 under high q/G conditions, in which buoyancy effect and variations in thermophysical properties were both taken into account.
