Abstract

The dynamics of spreading of viscous non-volatile fluid droplets on surfaces is modelled using a solid-on-solid model, which is studied with Monte Carlo simulations. Tendencies to dynamical layering and surface attraction are in part embedded into the effective dynamics of the model. This allows a description of the spreading process with a single parameter, which strongly influences the morphology of the droplets. The results qualitatively reproduce many experimentally observed density profiles for polymeric fluids, including rounded droplet shapes and dynamical layering.
