Molecular dynamics simulation has been performed on pairs of solid walls and liquid films in between. As a shear is given to the liquid film by moving the solid walls, the Couette-like flow is generated in the liquid film and energy conversion occurs from the macroscopic flow to the thermal one, i.e., viscous heating in the macroscopic sense. In such a way, momentum transfer and thermal energy transfer are present simultaneously. At the solid-liquid interfaces, there exist large velocity and temperature jumps due to the large momentum and heat fluxes. It has been revealed in our present study that the characteristics of the energy and momentum transfer at the interfaces are greatly influenced by the crystal plane of the solid walls which contacts to the liquid film.
