Modelling of momentum transport in a nanoscale liquid bridge

Abstract

Momentum transport phenomena in a nanoscale liquid bridge were analyzed by molecular dynamics simulations. Water was chosen as the lubricant. The effective viscosity coefficient of the liquid bridge was obtained from the ratio of the shear stress to the velocity gradient. Then the influence of the liquid bridge width on the effective viscosity coefficient was estimated. Moreover, the momentum flux are divided into two part, that in bulk region and that in boundary region. Using these fluxes, the effective viscosity coefficient in each region was estimated.
