Modeling and simulation of micro-rotation and spin gradient viscosity for ferromagnetic hybrid (Manganese Zinc Ferrite, Nickle Zinc Ferrite) nanofluids

Abstract

A common technique of enhancing thermal conducting is through the insertion of small magnetic particles or other nanoparticles with high thermal conductivity. In this research letter, manganese Zinc ferrite (MnZnFe2O4) and Nickle Zinc ferrite (NiZnFe2O4) were examined to assess the maximum possibility of enhancing thermal conductivity for current heat dissipation fluid problem. Therefore, a mathematical modeling is developed for steady, incompressible, 2D ferromagnetic hybrid (Manganese Zinc Ferrite, Nickle Zinc Ferrite) nanomaterial of micropolar fluid (non-Newtonian) towards moving surface of sheet. Darcy–Forchheimer porous medium effect is studied through momentum equation and thermal stratification effect is employed in heat equation. Micro-rotation and spin gradient effects are accounted. The model of heat diffusion initiated by Fourier law of heat conduction is implemented for energy transport assessment. The governing partial differential equations are altered through implementation of appropriate similarity variables into ordinary ones. Built-in-Shooting technique leads to the solutions of dimensionless flow equations. Behaviors of physical phenomenon are sketched by taking various positive estimations of concerning material constraints. The comparative solutions subject to manganese Zinc ferrite (MnZnFe2O4) and Nickle Zinc ferrite (NiZnFe2O4) hybrid nanofluids are presented and studied. From obtained results, we observed that velocity is more for MnZnFe2O4-NiZnFe2O4-C8H18 as compared to MnZnFe2O4-NiZnFe2O4-C10H22-C8H18 hybrid nanomaterials.
