A Molecular Dynamics Study of Evaporation and Condensation of Argon Droplet
Details
Molecular dynamics simulations of equilibrium state of argon vapor and its own spherical droplet are executed to investigate molecular processes of evaporation and condensation at the vapor-droplet interface. Equilibrium states at about 90K are computed for droplet radii raging from about 14Å to 42Å. Results show that outgoing and incoming molecular fluxes through a sphere enclosing a droplet increase with the decrease in the droplet radius. The equilibrium vapor pressure and density also become large as the droplet radius becomes small.
