Significance of MHD Micropolar Tri-hybrid Nanofluid Flow past a Stretched Surface with Modified Fourier and Fick’s Law

The persistent challenge of optimizing heat transfer and energy storage in industrial and engineering applications has spurred the development of advanced heat transfer fluids, such as nanofluids and hybrid nanofluids. A third-generation heat transfer fluid, known as modified hybrid nanofluids (MHNs), has recently emerged, created through the synthesis of ternary nanomaterials and the base fluid. This new class of fluids demonstrates enhanced effectiveness over simple nanofluids in a variety of engineering and industrial applications. Thus, the current analysis concentrates on a thorough investigation that employs modified versions of Fick’s and Fourier’s laws to explore a variety of scientific ideas in a synergistic manner, including magnetohydrodynamics, micropolar trihybrid nanofluids, second-grade fluids, and stagnation point flow. Additionally, the effects of thermal radiation, activation energy, viscous dissipation, and double stratification are considered. The study goes on to use the modified versions of Fourier’s and Fick’s principles, which offer a thorough foundation for comprehending heat-mass communication in such complex systems. By using suitable similarity variables, the flow model equations are converted into their non-dimensional forms. These non-dimensional equations are then numerically solved through the BVP4C technique implemented in MATLAB. Results are produced both numerically and graphically, and they are analyzed for different emergent dimensionless parameters. For both unary and trihybrid nanofluid flow, the thermal and concentration relaxation time parameters decrease the temperature and concentration profile. Furthermore, when ternary hybrid nanofluid and unary nanofluid are present, the fluid velocity and temperature flow rapidly increase with bigger values of the second-grade fluid parameters.
