Abstract
In this study, we have evaluated the force around the contact line by Molecular Dynamics Simulation. Using nine different-sized nano channel, we evaluated the channel size dependence of the friction force around the contact line region by one component of the stress tensor. Compared with the force evaluated by dynamic contact angles, we can say that in the case that the channel size is smaller than 10 nm, the friction forces evaluated by the shear stress do not agree with the force by the dynamic contact angles.
