Mixed convection flow of Eyring-Powell fluid along a rotating cone

In the present article, we have studied the unsteady boundary layer flow of a rotating Eyring-Powell fluid on a rotating cone with the combined effects of heat and mass transfer. The governing momentum, energy and mass equations for unsteady flow are presented and simplified using similar and nonsimilar transformations. The reduced coupled nonlinear differential equations are solved analytically with the help of a strong analytical technique namely the optimal homotopy analysis method. Numerical results for important physical quantities are computed and displayed. The physical features of suitable parameters are discussed through the graphs of velocities, heat transfer, concentration, skin friction, Nusselt number and Sherwood number. (C) 2014 The Authors.
