Abstract:

The nonlinear thin film rupture has been analyzed by investigating the stability of thin films under the influence of electrostatic field to finite amplitude disturbances. The dynamics of the liquid film is formulated using the Navier Stokes equations including a body force term due to van der Waals attractions. The effect of the electric field is included in the analysis. The governing equation was solved by finite difference method as part of an initial value problem for spatial periodic boundary conditions. A discussion is provided for the effect of the electric field strength on the film rupture.
