Abstract

Superhydrophobic surfaces play an important role in the development of new product coatings such as cars, but also in mechanical engineering, especially design of turbines and compressors. Thus a vital part of the design of these surfaces is the computational simulation of such with a special interest on variation of shape and size of minor pits grooved into plane surfaces. In the present work, the dependence of the contact angle on the fluid-wall dispersive energy is determined by molecular simulation and static as well as dynamic properties of unpolar fluids in contact with extremely rough surfaces are obtained.
