Homotopy Perturbation Method for MHD Boundary Layer Flow with Low Pressure Gradient over a Flat Plate

Abstract

Using He’s Homotopy Perturbation Method (HPM), the system of non-linear partial differential equations governing the MHD boundary layer equations with low pressure gradient over a flat plate are solved. The main advantage of HPM is that it does not require the small parameters in the equations and hence the limitations of traditional perturbation can be eliminated. The influence of various relevant physical characteristics are presented and discussed.
