Two analytical methods applied to study thin film flow of an eyring-powell fluid on a vertically moving belt

The purpose of this article is to investigate the thin film flow of an Eyring- Powell fluid on a vertically moving belt. The nonlinear equation governing the flow problem is modeled and then solved by applying the variational iteration method and the Adomian decomposition procedure. The numerical results obtained by these methods are then compared through graphs and very good agreement is observed. This study highlights the significant features of the proposed methods and their ability for solving nonlinear problems arising in non-Newtonian fluid mechanics.
