The present paper addresses the three-dimensional flow of an Eyring-Powell nanofluid by an exponentially stretching surface. Convective boundary conditions for both heat and mass transfer are employed. Similarity transformations are invoked to reduce the partial differential equations into the ordinary differential equations. Convergent series solutions to the resulting nonlinear problems are derived. Influences of physical parameters on the velocities, temperature and concentration profiles are discussed. Numerical values of local Nusselt and Sherwood numbers for all the involved physical parameters are computed and analyzed. A comparative study between the present and previous results is made in a limiting sense.
