Evaluation of heat transfer correlations for supercritical carbon dioxide in circular tubes under heating conditions

This paper presents a review of heat transfer correlations for supercritical carbon dioxide in circular tube under heating conditions. All of these reviewed correlations were preliminarily evaluated based on experimental data in open literature. The results showed that most of these heat transfer correlations have the general form of classical single phase heat transfer correlations with some modifications. Among these correlations, Jackson correlation and Krasnoshcheko correlation agreed well with experimental data, however, poor agreement was found for all of the reviewed correlations in near-critical region.
