This work deals with the three-dimensional flow of nanofluid over a bi-directional exponentially
stretching sheet. The effects of Brownian motion and thermophoretic diffusion of nanoparticles
are considered in the mathematical model. The temperature and nanoparticle
volume fraction at the sheet are also distributed exponentially. Local similarity solutions are
obtained by an implicit finite difference scheme known as Keller-box method. The results
are compared with the existing studies in some limiting cases and found in good agreement.
The results reveal the existence of interesting Sparrow-Gregg-type hills for temperature distribution
corresponding to some range of parametric values
