Temperature dependence of the thermal conductivity of molten NaCl by MD simulation with dipole interaction

Abstract:
The thermal conductivities of molten NaCl have been evaluated at temperatures from 1100 K to 1400 K by using molecular dynamics simulation with dipole interaction model. The results are in closer agreement with the experimental results by using the forced Rayleigh scattering method in comparison with previous calculation results by using the Fumi-Tosi potential model. While the results show an apparently negative temperature dependence, further calculations regarding both temperature dependence under constant density and density dependence under constant temperature reveal that the thermal conductivity depends strongly on density but only weakly on temperature in molten NaCl.
