Molecular dynamics study of flow at a fluid-wall interface

摘要: A novel wall model, including inelastic fluid-wall collisions, molecular structure of the wall, and a long-ranged interaction, is used in dynamics simulations flow two dimensions. For strong attraction fluid velocity goes smoothly to zero at wall; there no slip. In less dense fluids drops an ever-narrower region. Our results differ from standard kinetic theory but agree with Eu's theory. The nature interaction important; repulsive walls give slip
