Homotopy Solution for Stagnation-Point Flow

This article reports the homotopy solution for stagnation point flow of a non-Newtonian fluid. An incompressible second grade fluid impinges on the wall either orthogonally or obliquely. The resulting nonlinear problems have been solved by a homotopy analysis method (HAM). Convergence of the series solutions is checked. Such solutions are compared with the numerical solutions presented in a study [Int. J. Non-Linear Mech. 43 (2008) 941]. Excellent agreement is noted between the numerical and series solutions.
