Abstract
AbstractSurface wetting can be simulated using a phase field approach which describes the continuous liquid‐gas transition with the help of an order parameter. In this publication, wetting of non‐planar surfaces is investigated based on a phase field model by Diewald et al. [1, 2]. Different scenarios of droplets on rough surfaces are simulated. The static equilibrium for those scenarios is calculated using an Allen‐Cahn evolution equation. The influence of the surface morphology on the resulting contact angle is investigated while the width of the phase transition from liquid to gas is varied as a model parameter.
