It comprises of initial guess, auxiliary functions (containing unknown convergence controlling parameters) and a homotopy. The said method is applied to solve nonlinear Riccati equations and nonlinear BVP of order two for thin film flow of a third grade fluid on a moving belt. It is also used to solve nonlinear BVP of order three achieved by Mostafa et al. for Hydro-magnetic boundary layer and micro-polar fluid flow over a stretching surface embedded in a non-Darcian porous medium with radiation. The obtained results are compared with the existing results of Runge-Kutta (RK-4) and Optimal Homotopy Asymptotic Method (OHAM-1). The outcomes achieved by this method are in excellent concurrence with the exact solution and hence it is proved that this method is easy and effective. © 2016 Faculty of Engineering, Alexandria University date: 2016 publisher: Elsevier B.V. official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-84991784034&doi=10.1016%2fj.aej.2016.07.013&partnerID=40&md5=fb4a624a3ae89369f1788ee07f67c952 id_number: 10.1016/j.aej.2016.07.013 full_text_status: none publication: Alexandria Engineering Journal volume: 55 number: 3 pagerange: 2811-2819 refereed: TRUE issn: 11100168 citation: Ali, L. and Islam, S. and Gul, T. and Khan, I. and Dennis, L.C.C.
