Analytical solution for viscous flow over a nonlinearly stretching sheet: A homotopy perturbation approach

Abstract

This note is directed at highlighting the strength of the Homotopy Perturbation Method (HPM) over some known numerical and approximate methods. The HPM is employed to obtain the solution of a flow problem involving viscous incompressible fluid over a non-linearly stretching sheet. Aside the faster convergence of the method, a comparison made revealed that the HPM returns results with better accuracy than other approximate and numerical methods.
