Nanofluids are Nanoscale colloidal suspensions containing condensed nanomaterials. These fluids enhanced the thermal and physical properties in many areas. With this intention, we study the magnetohydrodynamic mixed convection flow over a cone in the presence of non-uniform heat source/sink and thermal radiation. In this study, we consider Cu-water nanofluid at 50�C and 10�C temperature variations. The model; used for the nanofluid is one which includes the Brownian motion and thermophoresis effects. The self-similarity transformed governing equations are solved by using Runge-Kutta technique. The physical characteristics namely, the friction factor coefficient, the rate of heat and mass transfer coefficients , velocity, temperature and concentration fields are discussed and analyzed through graphs and tables. Results indicate that the Cu-water nanofluid enhanced the temperature profiles at 50�C when comparison with 10�C for all flow parameters. Also, found that the heat transfer rate is higher at 10�C temperature when compared with the temperature at 50�C.
