Fluids on the nanoscale behave qualitatively different from macroscopic systems. This becomes particularly evident if a free liquid-liquid or liquid-vapor interface is close to a solid surface such as in the case of nanodrops or ultrathin films. Hydrodynamic slip, thermal fluctuations, the molecular structure of the fluid, and the range of the intermolecular interactions are important for the structure and the dynamics of such open nanofluidic systems.
Here we focus on a top-down approache to the theoretical description of fluids on the nanoscale : mesoscopically augmented hydrodynamic equations. We discuss their application to the dynamics of dewetting on homogeneous substrates as well as on the dynamics of nanpdroplets and rivulets on topographically or chemically structured substrates.
