Modified Optimal Homotopy Perturbation Method to Investigate Jeffery-Hamel Flow

A simple analytical approach is used to solve nonlinear problem forming in the phenomenon of Jeffery-Hamel Flow. The suggested technique consists of a homotopy with an embedding parameter, Daftardar-Gejji and Jafari polynomials (DJPs) and auxiliary functions. It has also some constants, used for controlling the convergence of the solution. The suggested technique is named Modified Optimal Homotopy Perturbation Method (MOHPM). The method is simple but effective and the results gained by this are in good agreement with numerical outcomes. The achieved results are compared with the results gained by Homotopy asymptotic method (HAM), Optimal homotopy asymptotic method (OHAM), Homotopy perturbation method (HPM), Modified Homotopy Perturbation Method (MHPM), Adomain decomposition method (ADM) and Differential transform method (DTM) to authenticate the code.
