A Simulation of Meniscus Formation Between Surfaces Having Two Dimensional Sinusoidal Roughness by Using Molecular Dynamics

Abstract

Using the molecular dynamics method has simulated three-dimensional meniscus formation on surfaces having two-dimensional sinusoidal roughness. Argon molecules were selected both for liquid and gas molecules moving with a constant temperature of 84K, and stationary solid molecules for solid surfaces. It is observed that the radius of curvature of meniscus varies with the solid-liquid interaction, and normal stress of meniscus is propotional to the curvature.
