Oham Solution of Thin Film Non-Newtonian Fluid on a Porous and Lubricating Vertical Belt

In this paper, problem of thin layer third order fluid flow past a vertical lubricating and porous belt that modeled by a system of nonlinear differential equations have been studied in the presence of heat. The nonlinear differentials equations for the fields of velocity and temperature have been solved analytically by using Optimal Homotopy Asymptotic Method (OHAM). The influence of different physical parameters on the velocity and temperature field have been studied and discussed. The comparison of present work with published work is also mentioned graphically and numerically.
