Abstract
PurposeThe purpose of this paper is to introduce a new version of the homotopy perturbation method (HPM) for solving the magnetohydrodynamic viscous flow due to a shrinking sheet.Design/methodology/approachThree terms from HPM solution are used.FindingsThe results show that this method is very effective and simple and can be applied to other nonlinear problems.Research limitations/implicationsComparison between the HPM and homotopy analysis methods for the studied problem shows a remarkable agreement and reveals that the HPM needs less work.Practical implicationsIt is suggested that this method should be called HPM with auxiliary parameters. This paper uses two auxiliary parameters, three or more auxiliary parameters could be used for accuracy consideration.Originality/valueIn this paper, a two‐parameter HPM is applied which is useful for finding an approximate analytical solution of MHD viscous flow due to a shrinking sheet.
