要約

In this article, the governing equations of magnetohydrodynamics (MHD) viscous flow over a stretching sheet are reduced to an ordinary boundary value problem using a similarity transformation. The new analytical approach multistep optimal homotopy asymptotic method (MOHAM) is formulated and used for the solution of the boundary value problem. The comparison of results of MOHAM with the homotopy perturbation method (HPM), exact solution, and numerical results (Runge-Kutta method) revealed that the new technique is a powerful method for solving boundary layer equations. Also, the solution is plotted for various values of β and M.
