On a solid substrate, superfluid may show stratified liquid films
(above a solid
layer). Assuming the existence of these films, we
analyse the
dynamics of wetting for a two-layer droplet which tends to spread and transform
into a one-layer droplet (at low temperature: no vapour phase is present). The
permeation process between layers, which exists in classical liquids, is
replaced
here by a Josephson coupling. Spreading should occur via Josephson vortices
that
drift towards the centre of the droplet.
