Structure formation in thin liquid films: Beyond the case of a single evolution equation

Abstract:
After presenting a short historical overview and basic experimental results we introduce a continuous model describing the time evolution of the film thickness profile of a single ultrathin partially wetting liquid film on a solid substrate. The model is used to discuss basic results on modes of film rupture [1].
Next, this one-layer model -- that represents an evolution equation for a conserved order parameter field -- is extended by regarding coupled evolution equations of (a) two conserved and (b) one conserved and one non-conserved order parameter. Cases (a) and (b) are illustrated studying pathways of rupture and coarsening for two-layer films [2] and the motion of chemically driven self-propelled running droplets [3], respectively.
