ABSTRACT

Nonlinear thin micropolar liquid film rupture has been analyzed by investigating the stability under the influence of a non-uniform electrostatic field to finite amplitude disturbances. The dynamics of the liquid film is formulated using the balance equations including a body force term due to van der Waals attractions. The effect of the electric field is included in the analysis only in the boundary condition at the liquid vapor interface. The governing equation for the film thickness was solved by finite difference method as part of an initial value problem for spatial periodic boundary conditions. The electric field stabilizes the film and increases the time to rupture when a long wavelength perturbation is introduced. The influence of material properties of the micropolar fluid on rapture is discussed.
