In the present paper, we propose a modified Molecular Dynamics (MD) simulation method to analyze a gas flow in nanometer scale narrow area placed between walls. In the method, we use the diffiise reflection model which assume that the wall is smooth and gas molecules reflect difiusely on the wall surfaces. This model is usually used in the direct simulation Monte Carlo (DSMC) method. Using the MD simulation method, the Couette flow problem, in which a gas flow is induced between two parallel plates separated by 10nm and running opposite directions by 785m/s, is analyzed numerically.
