The basic theme of this investigation is to analyze heat and mass transport for three dimensional (3D) stagnation flow of nanofluid caused by an exponentially stretched surface when water is treated as base fluid. In this study we invoked the boundary layer phenomena and suitable similarity transformation of exponential character, as a result our three dimensional non-linear equations of momentum and energy are transmuted into nonlinear and non-homogeneous differential equations involving ordinary derivatives. Final equations are than puzzled out by applying homotopy analysis technique. Interesting outcomes of aggressing parameters involved in this study, effecting profiles of temperature field and velocity are explained in detail. Different aspects of skin friction coefficient as well as Nusselt number are calculated at the end. Graphical results of involved parameters appearing in considered nanofluid are presented separately.
