This article discusses the way the standard description of capillary fillingdynamics has to be modified to account for liquid/solid slip in nanometricpores. It focuses in particular on the case of a large slip length compared tothe pore size. It is shown that the liquid viscosity does not play a role, andthat the flow is only controlled by the friction coefficient of the liquid atthe wall. Moreover in the Washburn regime, the filling velocity does not dependon the tube radius. Finally, molecular dynamics simulations suggest that thisstandard description fails to describe the early stage of capillary filling ofcarbon nanotubes by water, since viscous dissipation at the tube entrance mustbe taken into account.
