Overview

Experimental data and molecular dynamics simulation reveal high-temperature thermal properties in molten salts, suggesting significant heat storage capacity.

Key Points

  • The ternary eutectic salt shows outstanding heat storage capacity with a melting point of 852.65 K.
  • Specific heat capacity measures 1.268 J/(g K), and thermal conductivity slightly decreases with temperature.
  • Deep potential molecular dynamics simulation predicts viscosity decline from 3.117 to 1.755 mPa s and compares closely to experimental data.
  • Results validate the high accuracy of the DP model, indicating its potential application in thermal energy storage systems.
