Hydrodynamics and ferrite nanoparticles in hybrid nanofluid

Abstract

The solids have higher heat transfer rate comparative to fluids, thus, in the present article, two different ferrite nano-particles are suspended in two different base fluids to demonstrates its impacts on the friction drag and heat transfer. Ferrites nano-particles are used because of the existence of Curie temperature in these particles, a property that makes them distinct from other nano-particles. Distinct ferrites have different Curie temperature, this means that the presence of ferrite nano-particles in base fluids makes them efficient for heat transfer in ferromagnetic fluid flows. Thus, this article focuses to study two ferrites, i.e., Magnetite ferrite Fe3O4 and Manganese zinc ferrite MnZnFe2O4 with base fluids water H2O and refrigerant-134A C2H2F4. Heat transfer and friction drag are carried out for these hybridized ferrites nanoparticles in ferromagnetic nano-fluids. The higher velocity field is seen for the hybrid nanofluid MnZnFe2O4-Fe3O4-H2O-C2H2F4, whereas, the lowest velocity field is demonstrated for the nanofluid Fe3O4-H2O.
