The effects of mesoporous size and structure on the solidification characteristics of mixed nitrate were simulated by molecular dynamics (MD). The solar salt models of different scales are established by using material Studio software, and the models are exported to the Lammps software package for simulation calculation. The changes of parameters such as radial distribution function, potential energy temperature curve, freezing point, and phase transformation latent heat are summarized, and the micro mechanism of solar salt solidification characteristics at the nanoscale is analyzed. The results show that the freezing point of solar salt increases first and then decreases with the increase of nanopore size, and finally tends to be stable with the increase of nanopore size. The enthalpy of solidification decreases with the increase of scale.
