Evaporation of a thin liquid film

摘要

Evaporation of a thin (submicrometer size) liquid film confined between two solid substrates is studied using diffuse interface hydrodynamic model supplemented by the van der Waals equation of state.The time and space evolution of the basic thermodynamic quantities such as temperature,density,entropy,chemical potential,and entropy production is presented.The values of numerical parameters chosen correspond to those of argon.The time and space scales studied range from picoseconds to microseconds and from nanometers to micrometers correspondingly.
