Simulation of fluid flows in the nanometer: kinetic approach and molecular dynamic simulation

Slip phenomenon usually occurs at the fluid-solid interface as a fluid flows in a nanometer device. The slip length that characterizes the slip behavior depends on a variety of factors. In this work, the influences of the fluid-wall interaction and system temperature on the slip length for dense fluid flows are studied using a kinetic model and the molecular dynamic (MD) simulation. It is found that the results predicted by the both approaches agree with each other qualitatively.
