The heat transfer in a steady laminar stagnation point flow of an incompressible non-Newtonian micropolar fluid impinging on a permeable stretching surface with heat generation or absorption is investigated. Numerical solution for the governing nonlinear momentum and energy equations is obtained. The effect of the characteristics of the non-Newtonian fluid, the surface stretching velocity, and the heat generation/absorption coefficient on the heat transfer is presented.
