Liquid metal fast reactor/concentration solar power system coupled with supercritical carbon dioxide (S-CO2) Brayton cycle power system will surely lead the revolutionary development in the field of energy and power in future. Due to the special properties of liquid metal and S-CO2, the Pr number of liquid metals is low; the physical properties of S-CO2 steep varies in the pesudocrtical region, thus its flow and heat transfer characteristics are different from those of conventional fluids, their heat transfer mechanism is relatively complex, and the conjugated heat transfer mechanism is not clear. This study summarizes the main research results of supercritical CO2, liquid metal, conjugated heat transfer and conjugated heat exchanger at home and abroad in experiments, numerical simulation and prediction models, points out the problems in the research of CO2, liquid metals and their conjugating heat transfer between the two fluids, the discussion can provide valuable reference for the design and safe operation of advanced power cycle and multiple working fluids coupling power systems.
