Irreversibility analysis on tetra-hybrid non-Newtonian fluids with thermal radiation and Soret-Dufour effects over porous inclined stretching sheet

Present study suggests a comparative analysis of tetra hybrid Casson, Maxwell and tangent hyperbolic nanofluids with entropy generation to minimize the heat loss. The inclusions of thermal radiation for heat dissipation, Soret-Dufour effect for heat and mass transport coupling, slip boundary conditions for control of fluid flow and magnetic field with porous media for regulating fluid motion with these effects this study provides a comprehensive analysis of non-Newtonian tetra-hybrid nanofluid dynamics past the inclined stretching sheet. The numerical solution for the transformed ODE's is solved by fifth order Runge Kutta Felhberg method with shooting approach. An increase in magnetic parameter reduces entropy generation. The maximum skin friction coefficient is found in tangent hyperbolic hybrid nanofluid and it decreases by 25 % as the velocity slip parameter increases. The Casson tetra-hybrid nanofluid has a greater heat transfer rate, which increases by 52 % as Soret number increases. The comparison of non-Newtonian fluid is used to understand their diverse rheological behaviors that significantly influence their performance. Through this study, we can ascertain the most suited applications in aerospace, energy and biomedical engineering subject to enhance thermal regulation and heat transfer effectiveness. As a result, its findings can optimize the use of non-Newtonian tetra-hybrid nanofluids by influencing the design of heat exchangers, filtration systems, targeted drug delivery and cooling systems in these fields.
