摘要:

Molten salt is widely utilized as high-temperature heat transfer and storage medium. Firstly, the molecular dynamics and potential function of molten salt is summarized and analyzed in this work. Buckingham potential is more suitable for nitrate and fluoride molten salts, while BMH potential is better suited for carbonate and chloride molten salts. Secondly, the transport and thermophysical properties of molten salt and molten salt nanofluids are analyzed and summarized. The increase of Li+ concentration leads to higher specific heat capacity and thermal conductivity, and it increases simulation error. Increasing K+ concentration reduces specific heat capacity error but increases calculation error for other thermal properties. Carbonate simulations exhibit relatively small errors with good agreement with experimental data. Adding nanoparticles to molten salt is an effective method to enhance molten salt thermal physical performance. Future research directions in the field of molecular dynamics of molten salt encompass investigating the impact of nanofluids on molecular dynamics, mitigating simulation errors, exploring corrosion characteristics through molecular dynamics simulations. Largesized interface model and long-term scale are more effective for joint experimental and theoretical results according to the machine learning accelerated molecular dynamics research. More combinatorial properties such as corrosion characteristics can be explored through molecular dynamics simulations, providing a new basis for molten salt application.
