Comparative heat transfer analysis of electroconductive Fe3O4–MWCNT– water and Fe3O4–MWCNT– kerosene hybrid nanofluids in a square porous cavity using the non-Fourier heat flux model

The analysis of heat transmission and fluid flow characteristics within the cavity is useful to improve features several applications including energy storage devices hybrid fuel cells. With this motivation, present model investigates magneto-convective a square porous enclosure with hot cold slits. transfer electrically conducting nanofluids [Formula: see text] water kerosene are analyzed inside enclosure. non-Fourier thermal flux deployed, internal absorption/generation effect considered. marker-and-cell numerical scheme adopted solve transformed dimensionless mathematical associated initial–boundary conditions. An exhaustive parametric investigation implemented estimate influence key parameters on transport phenomena. computations show that augmenting Hartmann number values modifies temperature substantially for both nanofluids. Enhancing nanoparticles volume fraction promotes transfer. When 5% suspended into base fluids, nanofluid achieves 6.85% higher mean rate compared nanoliquid. In existence absorption, 78.92% lower than Greater noticed in case nanofluid, enhanced nanofluid. Fourier's estimates Cattaneo–Christov (non-Fourier) text].
