Abstract
Energy and momentum transfer at a solid-liquid interface has peculiar characteristics when shear at high rate is applied to the liquid by the moving solid wall. It has been showed in the previous report of ours on this problem for a monatomic liquid film that 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 the macroscopic sense. This phenomenon will be more complicated for the case with polyatomic liquid, where degree of freedom in rotational motion plays an important role in energy transfer. The present report is on the molecular dynamics study of this phenomenon, in which diatomic molecules are applied for the sheared liquid.
