Abstract: This research paper studies the impact of thermally radiative 3D viscoelastic nanofluid flow upon a stretchy paper with Newtonian heating. Appropriate similarity variables are used to remodel the governing non-linear PDEs to ODEs and they are analytically solved by adopting the homotopy analysis method (HAM). The disparity of fluid velocities, temperature, nanoparticle volume fraction, skin friction coefficients and local Nusselt number of various parameters is pointed out. It is noticed that, enhancing the Newtonian heating parameter increases the fluid temperature. Also found that the nanoparticle volume fraction enlarges with growing the thermophoresis parameter.

Keywords: viscoelastic; nanofluid; Brownian motion; radiation; Newtonian heating and thermophoresis effect; heat transfer; stretching sheet.
