Abstract: In this paper, a theoretical exercise on conducting nanofluid flow on stretching sheet in the presence of a heat source/sink is investigated. A buongiorno’s Nano scale formulation is developed to define the nanofluid model. By using an appropriate similarity transformation, the nonlinear partial differential equations are transformed into a nonlinear ordinary differential equation. The transformed system of differential equations are numerically solved using a MATLAB program. The effects of the blade velocity parameter, magnetic field parameter, Brownian motion parameter, thermophoresis parameter, Prandtl number, magnetic Prandtl number, thermal radiation parameter, Lewis number and heat source/sink parameter on the velocity, induced magnetic stream function gradient, temperature and nanoparticle concentration have been studied and presented graphically. The physical parameters such as skin friction function, local Nusselt number and Sherwood numbers are also computed and presented in tabular form. It is found that blade velocity parameter and magnetic Prandtl number increases the velocity whereas the magnetic field parameter suppresses the velocity. The temperature is enhanced with the Brownian motion, thermophoresis, parameter, radiation and heat source parameters and is suppressed with Prandtle number and heat sink parameters.
