T0501-1-5 Molecular Analysis of Momentum Transport Phenomena in a Nanoscale Liquid Bridge

Abstract

In this research the momentum transport phenomena in a nanoscale liquid bridge were simulated by Molecular Dynamics method and its nanoscale characteristics were analyzed. Water was assumed as the lubricant. Momentum flux was generated in a liquid bridge by controlling the velocity of a part of the liquid bridge. Using the velocity gradient of the liquid bridge and the momentum flux, viscosity coefficients of the liquid bridge were obtained. We analyze the dependence of the width of the liquid bridge on the viscosity coefficient and the differences of the viscosity coefficients between liquid bridges and bulk water were confirmed.
