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