摘要
In this paper, the homotopy perturbation method (HPM) and the Pade approximation are employed to investigate the magneto-hydrodynamic (MHD) boundary layer flow over a nonlinear stretching sheet, which occurs in many important engineering applications, such as the power generator, the cooling of reactors and the design of heat exchangers. The validity of results is verified by comparison with exact results and is shown in tables and graphs. It is found that the HPM is a user-friendly, powerful tool for solving complicated problems in physics and mathematics, and that in particular it has good accuracy as compared with exact results.
