Dynamics of capillary evaporation. II. Free energy barriers

Leung, Kevin L.; Luzar, Alenka

The free energy barriers of vapor tube formed in a metastable liquid confined between hydrophobic walls is investigated. Monte Carlo simulations, the transition state theory and constrained umbrella sampling techniques are performed to estimate the free energy barrier for vapor tube formation. Transmission coefficients calculated for the liquid layer show that capillary evaporation are also described from the size of a vapor pocket formed between the walls.
