Abstract: This paper studied two-dimensional steady laminar flow over a porous medium stretching surface with suction or injection. The homotopy analysis method, a kind of analytical method, was applied to solve the problem. The solution presents representative profiles for the dimensionless velocity and the skin friction coefficient at different permeability and injection parameters.
