The Couette flow of an ultra-thin liquid film between solid surfaces has been studied by a molecular dynamics simulation. A liquid of diatomic molecules and liquid water were assumed for the film liquid, and transfer of energy and momentum both in liquid film and at the solid-liquid interface was analyzed. It was revealed that the flow has peculiar characteristics when shear at high rate is given to the liquid due to velocity difference between the two solid walls. Highly nonequilibrium energy distribution occurs in the liquid just close to the solid surface in the process of energy conversion from flow to thermal one, i.e., viscous heating in a macroscopic sense, and energy transfer among degrees of freedom for rotational motion of molecules and translational one.
