  Understandings heat transfer across a solid/liquid interface is important to
develop new pathways to improve thermal management in various energy
applications. One of the important questions that arises in this context is the
impact of three-phase contact line between solid, liquid and gas on the
perturbations of the heat fluxes at the nanoscale. Therefore, this paper is
devoted to the investigations of features of thermal transport across nanosized
meniscus constrained between two solid walls. Different wetting states of the
meniscus were considered with molecular dynamics approach by the variation of
the interactional potential between atoms of the substrate and the liquid. The
effect of the size of the meniscus on the exchange of energy between two solid
walls was also investigated. It was shown that the presence of a three phase
contact line leads to a decrease of the interfacial boundary resistance between
solid and liquid. Further, investigations with the finite element method were
used to link atomistic simulations with the continuum mechanics. We demonstrate
that the wetting angle and the interfacial boundary resistance are the required
key-parameters to perform multiscale simulations of such engineering problems
with an accurate microscale parametrization.
