In this paper we have investigated the unsteady flow to thin films of an incompressible liquids with no inertia force, continuity equation and Nervier-Stokes equations are used to obtain the equation that governs this type of flow, this equation is solved analytically to find the thickness of the film.

The aim of this paper is to investigate the vertical flow in thin films of an incompressible liquids with no inertia force. Continuity equation and Navier-Stokes equations are used to obtain the equation that governs this type of flow, this equation is solved by using numerical methods to find the thickness of film.

In this paper we have investigated viscous flow in symmetric thin liquid films which are inclined by an inclination angle  to the horizontal for an incompressible liquids in two dimensions with no inertia force. We use the (Navier-Stocks) equations and we obtain equations that govern such flow and we solved these equations by numerical methods to obtain the thickness of the film.
