Abstract

A supercritical water heat transfer test section has been built at Xi’an Jiaotong University to study heat transfer in annular flow channel. Based on the experimental results, the effects of mass flux and heat flux on heat transfer of supercritical pressure water in vertical annular channel were analyzed. The characteristics and mechanisms of heat transfer enhancement, and that of heat transfer deterioration, were also discussed. Based on a comparison with two identical flow geometries with and without helical wrapped spacer, it was found that the spacer has a positive effect in enhancing the local heat transfer, especially in the pseudo-critical region.
