Stability and rupture of nano-liquid film (NLF) flowing down an inclined plane

The two-dimensional flow of a nano-liquidfilm (NLF) down an inclinedplane is represented by Navier–Stokes equation accounted for van der Waals and gravity forces. A long wave perturbation method obtains a non-linear evolution equation for the film interface. A linear theory for infinitesimal perturb...

A long wave perturbation method obtains a non-linear evolution equation for the film interface. A linear theory for infinitesimal perturbation is derived to obtain an estimate of the filmrupture time. The finite amplitude instability is quantified based upon numerical solution of the evolution equation using a finite difference technique. The predictions of the non-linear and linear theories are compared. van der Waals force play dominant role in the filmrupture for lower thicknesses (≤100 nm), whereas gravity controls the instability in higher thicknesses (>100 nm).
