Abstract

Molecular dynamics simulation has been performed on a liquid film sheared in between solid walls. 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, large jumps in velocity and temperature according to the large momentum and heat flux are observed. It has been revealed in the 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 contact the liquid film.
