A molecular simulation is developed to study the effect of surface nanostructures on nanoscale flows. Based on this method, particles equation of motion is solved through the Verlet algorithm. Meanwhile, a physically sound method is applied to control the momentum and temperature of the simulation box. By adding an external force on the top copper plate according to the velocity difference between on-the-fly and desired velocities, simulations on convection of argon flows between two solid walls are performed. The top wall, which holds a higher temperature, moves at a constant velocity relative to bottom one along with the streamwise direction. These simulation results show that the nanostructures particularly affect fluid density oscillations adjacent to solid wall and nanostructures. In addition, these nanostructures also have significant effects on temperature and velocity distributions in simulation system.
