This study addresses the novel characteristics of infinite shear rate viscosity and entropy generation in magneto-mixed convective flow of cross-nanomaterial toward a stretched surface. Moreover, analysis of current research work has been prepared for Brownian moment and thermophoresis deposition. Radiation and viscous dissipation aspects are accounted. More specifically, roles of activation energy and Lorentz force on nanofluids transportation are examined. ODEs are acquired from PDEs via

Discussion on rheological parameters involved in current research work is presented through graphs. Results demonstrate the significant rise in temperature and nanoparticles concentration with the intensification of Brownian moment aspects. More specially, we perceived that entropy rate is significantly affected by radiation parameter and Brinkman number. Intensification in entropy rate is observed for rising values of magnetic parameter, radiation parameter and Brinkman number.
