| Outline of Final Research Achievements |
The effect of quantum effect of hydrogen molecule on the thermal properties and transport phenomena of liquid hydrogen was analyzed. Both the centroid molecular dynamics method and classical molecular dynamics method was used. As for the thermal properties, the difference of its characteristics from principle corresponding state which cannot be explained on the standpoint of classical dynamics was clearly explained by considering the quantum effect of hydrogen molecule. As for the transport phenomena, diffusion coefficient of hydrogen molecule do not change even though the quantum effect was considered. The thermal conductivity of liquid hydrogen by considering the quantum effect become smaller than that by evaluating the standpoint of classical dynamics.
