A study on magneto-hydrodynamic non-Newtonian thermally radiative fluid considering mixed convection impact towards convective stratified surface

Enhancement of heat transportation is an immensely vital topic in industrial and engineering utilizations these days. Cooling liquids like water, propylene glycol (PG) and ethylene glycol (EG) having lower conductivity are utilized as unadulterated liquids in various applications, therefore rationing the heat transportation enhancement. Nonetheless, state-of-the-art fluids (nanoliquids) were recommended with a view to procure enhancement in thermal efficacy. Therefore the Buongiorno nanoliquid model highlighting better thermal efficacy in comparison to aforesaid standard cooling liquids is considered to formulate and analyze the non-Newtonian Casson liquid considering stretchable cylindrical surface. Flow is stratified and mixed convected due to consideration of thermo-solutal stratifications and thermo-solutal buoyancy forces respectively. In addition, Robin conditions, magnetic field and radiation effects are accounted. Differential form is obtained by introducing relevant variables. Homotopy procedure leads to convergent solutions of strong non-linear systems. The plots of significant factors are divulged through graphs.
