Thin Film Evolution

Abstract: R.J. Braun and A.D. Fitt came up with the thin film equation, which included the impact of fluid dynamic, pressure, gravity and more. This equation designed to study the aqueous layer on the eye surface. Rather than looking at the original equation, instead we will study two modification equations. One, the evolution equation using Beavers-Joseph boundary condition. And, the evolution equation is using Le Bars & Worster boundary condition. These two equations will explain the characteristic behavior of the fluid velocity and viscosity on the shear stress on the surface of an eye include the porous media layer (contact len). This study hope to explain the cause of dry-eye syndromes.
