Heat transfer enhancement of magnetized nanofluid flow due to a stretchable rotating disk with variable thermophysical properties effects

Ferrofluid is a one-of-a-kind substance that functions both as magnetic solid and liquid. In this article, water-based Fe3O4 Mn–ZnFe2O4 nanofluids between parallel stretchable spinning discs are considered. To carry out the study, influence of rotational viscosity in flow, which due to difference rotation fluid particles, applied field examined. Additional impacts incorporated novelty model variable thermal conductivity. The Legendre-based collocation method used solve set governing equations. ensure code validity, comparison with analytical results conducted an excellent consensus accomplished. Comparisons pertinent parameters on flow profiles displayed tabular graphical forms. Analyses reveal ferromagnetic nanofluid shows higher conductivity strength than nanoparticles. This study finds its usefulness aerospace, biotechnology, medical sciences, material so on.
