摘　　要：With the advantages of low cost,excellent ability of heat and mass transfer and easy accessibility to the supercritical point,supercritical CO_(2) has been applied in many engineering devices recently.Because of the sharply-varying thermophysical properties near the supercritical point,heat transfer and flow behavior of supercritical CO_(2) in tubes become complex and have received a lot of research attention.The main purpose of this paper is to summarize the findings of the published works related to flow phenomena and heat transfer characteristics of supercritical CO_(2).Firstly,influence parameters related to boundary conditions of supercritical CO_(2) flowing in a smooth tube are introduced.Secondly,commonly-used turbulence and mathematic models dealing with internal flows of supercritical CO_(2) are summarized.Then,research works on geometric effects of design parameters,shapes and configurations are introduced.The practical applications of supercritical CO_(2) in recent years are presented.Finally,developments and future challenges of supercritical CO_(2) in tubes are analyzed and summarized.This paper provides basic knowledge of heat transfer and fluid flow mechanisms and related practical applications of supercritical CO,in tubes.
