Abstract
The molecular dynamics computational method is used to simulate meniscus fo rmation around an asperity in a rough surface represented as a sinusoidal w ave. Simulation results show that the meniscus formation depends on the int eraction potential between the solid wall and the liquid atoms. For complet ely and partially dry substrates a meniscus cannot form around an asperity. For partially and completely wetting substrates the asperity helps to adso rb the fluid atoms and form a meniscus. These simulation results confirm th at if the film thickness exceeds a critical value, the capillary pressure c ontributes strongly to stiction. (C) 2001 American Institute of Physics.
