Abstract: This paper presents a review of typical heat transfer correlations for S-CO₂, and all of these reviewed correlations were preliminarily evaluated based on amounts of experimental data in published literatures. The results show that there exists superior difference between the predicted and experimental Nusselt numbers in the near critical region, and the predicting ability of these correlations are limited in the stage of deteriorated heat transfer recovery. The correlation of Dong Eok Kim and Moo Hwan Kim gives the best agreement with the test data used, with 84.53% of the predicted Nusselt numbers within a margin of error of ±30%. We also carried out an analysis on the structure of the correlations based on the former evaluation.
