Evaporation of Tiny Water Aggregation on Uniformly Complete Wetting Surface with Different Temperatures

Abstract

The evaporation of nanoscale water film on surface affects many processes in nature and industry. Using molecular dynamics (MD) simulations, we show the evaporation of nanoscale water film on a uniformly complete wetting surface at different temperatures. With the increase of the temperature, the growth of the water evaporation rate becomes slow. Analyses show that, the hydrogen bond (H-bond) lifetimes and orientational autocorrelation times of outermost water film decrease slowly as the increase of temperature. Compared to the thicker water film, the H-bond lifetimes and orientational autocorrelation times of monolayer water film are much slower. This suggests that the lower evaporation rate of monolayer water film on uniformly complete wetting surface may be caused by the constriction of the water rotation from the substrate. This finding may be helpful for controlling nanoscale water evaporation within a certain range of temperatures.
