Fluid Molecular Drive in a Nano-Channel Due to Intermolecular Potential Gradient

Abstract

Molecular flow induced by intermolecular potential gradient between solid and fluid was analyzed by a MD method. Platinum (Pt) and xenon (Xe) were used as solid and fluid respectively. The number of Xe molecules was 100 and that of Pt atoms composing walls of nano-channel was 2400. The wall temperature was fixed at 300K. It was found that a longitudinal rotating flow in the nano-channel could be driven by the potential gradient.
