Steady two-dimensional stagnation point flow and heat transfer of a nanofluid over a porous stretching sheet is investigated analytically using the Homotopy Analysis Method (HAM). The employed model for nanofluid includes two-component four-equation non-homogeneous equilibrium model that incorporates the effects of Brownian diffusion and thermophoresis simultaneously. The basic partial boundary layer equations have been reduced to a twopoint boundary value problem via similarity variables. The effects of thermophoresis number (
