Abstract:

 Molten salt-based nanofluids is a heat transfer fluid formed by adding nano-particles on the basis of molten salt, which can remarkably enhance the specific heat capacity and thermal conductivity of molten salt, reduce the viscosity of molten salt, and increase the heat storage density and reduce the heat storage cost is of great significance, it has become the focus of attention at home and abroad to study new medium-temperature heat transfer media. In order to further study the molten salt nanofluids to provide direction. In this paper, the latest research progress of molten salt-based nanofluids in recent years is summarized, including the preparation method, thermophysical properties and convective heat transfer of molten salt-based nanofluids. And put forward the technical problems that need to be solved in the future of molten salt-based nanofluids.
