摘要
The evaporation and condensation processes of argon at the liquid-vapor interface are investigated with molecular dynamics (MD) simulations. By introducing a novel statistical method, namely, the characteristic time method, the condensed then re-evaporated molecules are successfully distinguished from the reflected molecules according to their different characteristic times, which are estimated based on the statistic during simulation. The kinetic characteristics of the condensed, reflected, and evaporated molecules are separately studied and compared. The results show that the high kinetic energy component normal to the interface is an important character of the interphase transport process.
