Abstract

This study proposed a sophisticated numerical model based on geometry constraints and force equilibrium on the water/air interface in order to compute the meniscus profile and the adhesion forces between a semispherical probe tip and a rough surface under humid conditions. Through the proposed method, the unusual concave curve for the adhesion force results can be understood in detail. The effects of the contact angles of the probe tip and the asperity on the adhesion force were also discussed.
