In this paper, we use variational iteration method (VIM) to handle the foam drainage equation. Foaming occurs in many distillation and absorption processes. The drainage of liquid foams involves the interplay of gravity, surface tension, and viscous forces. The results reveal that the variational iteration method (VIM) is more efficient than the ADM and it is very effective, convenient and quite accurate to systems of non-linear partial differential equations. It is predicted that VIM can be found widely applicable in engineering.
