Many thin fluid films are subject to instabilities caused by a competition of short and long range intermolecular forces. After breaking into droplets connected by an ultra-thin film, the fluid will undergo a coarsening process in which droplets both move and exchange mass on slow timescales. In the context of a one-dimensional lubrication model, the slow dynamics can be characterized in terms of a finite dimensional set of evolution equations. From this, a scaling law which governs the coarsening rate is derived.
