Abstract: This paper presents an investigation of the hydromagnetic boundary layer flow of a nanofluid and heat transfer past a porous exponentially stretching sheet with effects of heat generation/absorption and Ohmic heating. The impact of Brownian motion and thermophoresis on heat transfer, thermal radiation, chemical reaction and viscous dissipation are also considered. Nonlinear partial differential equations governing the motion are reduced to ordinary differential equations by using similarity transformations. These equations are solved numerically using the Nachtsheim-Swigert shooting technique scheme together with Fourth-order Runge-Kutta integration method, for different values of flow parameter such as magnetic interaction parameter, porosity parameter, Brownian motion, thermophoresis parameter, Eckert number, heat source/sink parameter, Lewis number, chemical reaction parameter, and suction parameter. Quantities of physical interest such as skin-friction coefficient, non-dimensional rate of heat and mass transfer are solved numerically and are tabulated. Comparisons with previously study are performed and are found to be in a good agreement.
