摘要
This study investigated the characteristics of lubrication rheology for polymer fluids using the molecular dynamics method. The confining potential and FENE potential were used to describe the bonding force in a polymer chain. Both Poiseuille and Couette flows were simulated and the results are presented for the density distribution, velocity profiles, slip ratio, viscosity, and relation between shear stress and shear rate. The effects of the number of molecular layers and film thickness on the rheology characteristics were also investigated.
