Theoretical study on thermal efficiencies of Sutterby ternary-hybrid nanofluids with surface catalyzed reactions over a bidirectional expanding surface

Abstract

The key focus of this study is to explore the flow and heat transfer characteristics of a blood-based composite nanoparticles consisting of the Al2O3, SiC, and MWCNT on a Sutterby fluid over a bidirectional porous stretching surface. These ternary-hybrid nanomaterials (Al2O3, SiC, and MWCNT) exhibits remarkable thermal conductivity attributes and enhances heat transfer in fluids. In the presence of modified heat flux model and surface-catalyzed reactions, the investigation of heat and mass transfer is carried out. Further, the impact of velocity partial slip and thermal convective conditions are taken into description at the surface of the bidirectional expanding surface. The developed flow model is converted into set of couple nonlinear ODEs with suitable transformation and use the bvp4c approach on MATLAB to get the numerical solution. The analysis considers for ternary-nanoparticles (Al2O3+SiC + MWCNT) and unary (Al2O3) nanoparticles, and provides comprehensive description among both for various emerging parameters. The graphical finding shows that in the presence of Darcy-Forchheimer, the reduction is occurred in the fluid velocity significantly for tri-hybrid and unary nanofluid, also same trend is seen for the slip parameter.
