Three-dimensional flow of Eyring Powell nanofluid over an exponentially stretching sheet

Purpose - The purpose of this paper is to analyze the Eyring Powell fluid over an exponentially stretching surface. Heat and mass transfer effects are taken into account with nanoparticles. Design/methodology/approach - Appropriate transformations are employed to reduce the boundary layer partial differential equations into ordinary differential equations. Series solutions of the problem are obtained and impacts of physical parameters on the velocities, temperature and concentration profiles are discussed. Findings - 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. Local Nusselt number -theta'(0) increases by increasing epsilon, Pr, lambda and N while it decreases for delta, N_{t},N_{b} and Sc. Originality/value - This analysis has not been discussed in the literature yet.
