homogeneous and inhomogeneous two‐dimensional parabolic equation. Also, we apply
our combined method for coupled Burgers' equations. The numerical results demonstrate
that our combined method gives the approximate solution with faster convergence rate and
higher accuracy than using the classic homotopy perturbation method.© 2010 Wiley
