The motive of the current investigation is to present a comparative study of entropy generation on Newtonian and Non-Newtonian fluids. Heat transfer of the slip flow over a melting expending surface, is investigated with an imposed heat source and non-uniform radiation. Uniform inclined magnetic field is also applied and medium is considered porous. A further non-linear chemical reaction is also studied. Non-Newtonian Williamson fluid is taken and compared with viscous Newtonian fluid. The developed dimensionless governing equations by using proper similarity transforms are solved with Runge-Kutta method of order four with shooting technique and numerical outcomes are described for various non-dimensional physical parameters by the graphs. From the results after comparing with available literature, it is concluded that the entropy generation can be increased with higher magnetic field parameter, parameter of porosity and inclination angle α of magnetic field and opposite behavior is seen with decreasing values of slip parameter for both fluids. With increasing the melting surface parameter, the thickness of the temperature profile get cut down.
