The thin film equation can be used to simulate several behaviors of liquids, such as the fingering instability in gravity driven flow. [14] The lack of a second-order time derivative in the thin-film equation is a result of the assumption of small Reynold's number in its derivation, which allows the ignoring of inertial … See more In fluid mechanics, the thin-film equation is a partial differential equation that approximately predicts the time evolution of the thickness h of a liquid film that lies on a surface. The equation is derived via lubrication theory which … See more • Partial differential equation • Lubrication theory • Disjoining pressure See more • Viscous Thin Films - Max Planck Institute See more The basic form of a 2-dimensional thin film equation is $${\displaystyle {\frac {\partial h}{\partial t}}=-\nabla \cdot \mathbf {Q} }$$ where the fluid flux $${\displaystyle \mathbf {Q} }$$ is See more Physical applications, properties and solution behaviour of the thin-film equation are reviewed in.
