Abstract:Under the condition of partial surface wettability, thin liquid films can be destabilized by small perturbations and rupture into droplets. The thin film equation (TFE) is one of the most popular theoretical approaches to describe this mechanism, but it is limited in principle to small equilibrium contact angles and ratios = h/L of film height h and lateral size L. Here, we use a multicomponent lattice Boltzmann (LB) approach to investigate systematically the stability of thin films in contact with a flat surf… Show more
