Critical Nanopore Diameter for Evaporation is 4 nm

Evaporation studies of water using classical molecular dynamics simulations are largely limited due to their high computational expense. This study addresses this issue by using a coarse-grained molecular dynamics model for evaporation of water on solid surfaces by combining four water molecules into a single bead. The Morse-D water model which accurately predicts the water properties at higher temperatures is used to study the evaporation from hydrophilic nanopores. The simulation results show that 4 nm is the critical diameter to initiate continuous evaporation at nanopores.
