| Popis: | Molecular dynamics simulations of equilibrium structures and Couette flows of polar water molecules and nonpolar argon atoms between bounding carbon substrates disposed at the distance h = 1.5 nm from each other have been performed. Two symmetric configurations when both substrates have similar, either graphene - like crystalline or amorphous structures, and one asymmetric configuration consisted of one substrate with graphene - like crystalline structure and another substrate with amorphous structure have been considered. It has been found that, in all configurations under consideration, the Couette flow velocity profiles depend strongly on polarity of fluid particles confined between bounding substrates. It has been also found that, for substrates with different structures, the Couette flows depend strongly on which of the substrate is moving and which is fixed. |
