Molecular dynamics simulations were performed to analyze momentum transport phenomena in a nanoscale liquid bridge. 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. The effect of the width of liquid bridge on the effective viscosity coefficient was estimated. Moreover, the momentum flux are divided into two parts, that in bulk region and that in boundary region. Using these fluxes, the effective viscosity coefficient in each region was estimated.
