Unsteady Flow of Horizontal Thin Liquid Films
In this paper we construct a mathematical model to describe the unsteady incompressible flow with negligible
inertia of a horizontal symmetric double -sided thin liquid films in two dimensions. We apply the Navier – Stokes equations
with an appropriate boundary conditions to obtain the non – linear differential equation of the film thickness.
