| Outline of Final Research Achievements |
Molecular Dynamics simulations of the dynamic wetting behavior of argon droplet on a solid surface as well as static behavior of water-alcohol mixture droplet were performed. For the former, by using the ensamble average technique, the spatial distributions of the density, velocity and stress tensor were extracted during the whole process of the dynamic wetting, and it was indicated that there exists a strong correlation between the solid-liquid velocity difference and the stress near the contact line of the droplet and this largely affects the dynamic wetting behavior. For the latter, the solid-liquid, liquid-vapor, solid-vapor interfacial tensions were independently evaluated in quasi-one-dimensional systems from mechanical and theromdynamic points of view, and showed that the balance among these tensions hold at the contact line of the droplet system.
