Unsteady Flow in a Horizontal Double-Sided Symmetric Thin Liquid Films
Journal Title: INCAS BULLETIN - Year 2017, Vol 9, Issue 2
Abstract
In this paper a mathematical model is constructed to describe a two dimensional incompressible flow in a symmetric horizontal thin liquid film for unsteadies flow. We apply the Navier-Stokes equations with specified boundary conditions and we obtain the equation of the film thickness by using the similarity method in which we can isolate the explicit time dependence and then the shape of the film will depend on one variable only.
