This paper presents comparison between optimal homotopy asymptotic method and homotopy perturbation method for the solution of two-dimensional steady flow of an incompressible Maxwell fluid over a transpiration channel within a porous medium due to a impulsively moving wall. The results obtained using HPM for injection case fails to be in accordance with the available analytical data.
