The application of second law of thermodynamics to an electrically conducting incompressible nanofluid slip flow over a stretching sheet is investigated in the presence of thermal radiation and non-uniform heat source/sink, both analytically and numerically. The governing dimensionless equations for this investigation are solved analytically by hypergeometric function and numerically by using Runge-Kutta-Gill method with shooting technique. The eects of magnetic parameter, nanosolid volume fraction parameter, slip parameter, and suction parameter on velocity prole are discussed for Ag nanoparticles. Further, in addition to these parameters, the eects of radiation parameter and non-uniform heat source/sink parameters on temperature prole and entropy generation number are also discussed. Finally, the results of these proles of Ag nanoparticles are compared with those of the Cu, Al2O3, and TiO2 nanoparticles. It is inferred that the eect of slip and non-uniform heat source parameters decrease the entropy generation. The metallic nanoparticles create more entropy than the non-metallic nanoparticles.
