The interaction of Polystyrene nanoparticles in the presence of entropy generation optimization along the magnetite Riga plate is the major concern of this study. The analysis deals with entropy generation minimization is well established approach to imrove the efficiencies of the thermal characteristics. The performance of nanofluid is studied over a stretchable Riga plate. The water and Kerosene based Polystyrene nanoparticles is exercised to examine the influence of nanoparticles on flow and heat transport features in the region around the stagnation point. The velocity slip mechanism is accounted to observe the modification in flow field. A study is also carried out to analyze the heat transport phenomenon under the the aspects of viscous dissipation and thermal stratification. Additionally, the stimulus of realistic and more general melting surface condition is presented. The problem is modeled in view of Tiwari-Das model. The reduced governing equations are solved analytically using convergent scheme. To predict the behavior of flow velocity, entropy generation and fluid temperature against the significant involved parameters, the curves are plotted and analyzed. Skin friction coefficient and Nusselt number are also shown through graphs. Results depict that entropy generation minimizes by intensifying melting parameter and further in entropy generation minimization, the effect of water-polystyrene nanofluid is dominant over kerosene-polystyrene nanofluid.
