The viscous coefficient comparison between 2-D and 3-D fluid models in molecular dynamics simulations

In this paper, 2-D and 3-D fluid models are calculated using equilibrium molecular dynamics simulation, the viscous coefficient and pressure are obtained under periodic boundary. By comparing and analyzing the differences of viscous coefficient and pressure curves between 2-D and 3-D fluid models, the way for how to use 2-D model to get the accurate viscous coefficient is found, the feasibility of 2-D model is discussed.
