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.

In this study, The steady flow of and within horizontal thin liquid symmetric double-sided film is considered. The nonlinear differential equations that govern such flow are derived from the Navier-Stokes equation. The solution curves are obtained numerically by using MATLAB software for two nondimensional cases. Numerical method and MATLAB are used to obtain the solutions and plot the curves for the result nonlinear differential equation and for number of fluids
