Irreversibility Analysis of Electromagnetic Hybrid Nanofluid Over a Stretchable Surface with Cattaneo-Christov Heat Flux Model: Finite Element Approach

To get a better heat transmission capacity of ordinary fluids, new hybrid nanofluids (HNFs) with a considerably greater exponent heat than nanofluids (NFs) are being used. HNFs, which have a greater heat exponent than NFs, are being applied to increase the HT capacities of regular fluids. Two-element nanoparticles mixed in a base fluid make up HNFs. This research investigates the flow and HT features of HNF across a slick surface. As a result, the geometric model is explained by employing symmetry. The technique includes nanoparticles shape factor, Magnetohydrodynamics (MHD), porous media, Cattaneo-Christov, and thermal radiative heat flux effects. The governing equations are numerically solved by consuming a method known as the Galerkin finite element method (FEM). In this study, H 2 O-water was utilized as an ironic, viscous improper fluid, and HNF was investigated. Copper (Cu) and Titanium Alloy (Ti 6 Al 4 V) nanoparticles are found in this fluid. The HT level of such a fluid (Ti 6 Al 4 V-Co/H 2 O) has steadily increased in comparison to ordinary Co-H 2 O NFs, which is a significant discovery from this work. The inclusion of nanoparticles aids in the stabilization of a nanofluid flowing and maintains the symmetry of the flow form. The thermal conductivity is highest in the boundary-lamina-shaped layer and lowest in sphere-shaped nanoparticles. A system's entropy increases by three characteristics: their ratio by fractional size, their radiated qualities, and their heat conductivity modifications.
