In this work, we investigate the validity of the Navier-Stokes (NS) equations for nanoscale liquidflows through molecular dynamics simulations. We focus on the role of channel size by considering the fluid-wall interaction.Liquidflows between two planar parallel walls driven by an external force with channel size ranging from 2 to 80 nm are studied. The volumetric flux is computed and the dependence of the volumetric flux on the channel size is explained both qualitatively and quantitatively. It is found that the flow is sensitive to the fluid-wall binding energy and the classical fluid mechanics falls apart in small nanochannels. However, the wall effects become insignificant and the NS equations are valid when the channel size is larger than about 150 molecular diameters (∼ 50 nm).
