Molecular dynamics simulation of evaporation coefficient of vapor molecules during steady net evaporation in binary mixture system

In this study, an evaporation coefficient representing the rate of vapor molecules was calculated in a vapor–gas binary mixture and non-equilibrium system using molecular dynamics simulation. The herein refers to state which net occurs, calculation is composed non-condensable (NC) gas molecules. demonstrated have almost same value as that equilibrium state. number density NC around gas–liquid interface, related probability are prevented from evaporating owing collisions, shown be independent This makes regardless whether or non-equilibrium. contrast, decreased molar fraction increased. increase causes higher leading prevents evaporating. Moreover, it clarified change interface structure caused by presence affects velocity distribution
