Molecular dynamics simulations are used to characterize the permeation by water of cylindrical nanopores, modelling ion channels, as a function of channel radius R and dielectric permittivity . Intermittent permeation is found in a narrow range around the threshold values of R and . While channel permeation is highly sensitive to channel polarization effects, no effect on structural properties of the confined water is found on varying .
