摘要

Due to its good thermophysical properties, CO2 has broad application prospects in system heat exchange. Recently, domestic and foreign scholars have conducted in‐depth research on the heat transfer in supercritical CO2 pipe. However, Because the physical properties of supercritical CO2 change sharply near the critical point, the relevant experimental research data obtained by scholars are not universal. By analyzing the research papers of domestic and foreign scholars on the heat transfer in supercritical fluid pipe in recent years, this paper summarizes the law of supercritical CO2 flow and heat transfer. By comparing the experimental conclusions of scholars, find out the accurate and persuasive part. In the end, the flow and heat transfer laws of supercritical CO2 in vertical and horizontal tubes are summarized, the quantitative effects of buoyancy and flow acceleration on heat transfer are analyzed, and some suggestions on the current research of heat transfer in supercritical fluid tubes are put forward.
