Hybridized two phase ferromagnetic nanofluid with NiZnFe2O4 and MnZnFe2O4

Abstract

Heat transfer analysis is important factor in the electronic and engineering equipment. For this purpose, engineers and scientists studied different models in this direction. Different solid particles are tried for the enhancement of thermal properties of base fluids. In this direction, ferrite nanoparticles, i.e., Nickel zinc ferrite NiZnFe2O4 and Manganese zinc ferrite MnZnFe2O4 is suspended in the base fluid kerosene C10H22 oil and engine C8H18 oil. The resultant suspension is analyzed in presence of a dipole placed externally, thus the fluid is known as hybrid ferromagnetic nanofluid. The stagnation point flow is analyzed in presence of Newtonian heating as well. The mathematical modeling of the flow is presented. It is demonstrated that the hybrid nanofluid has better performance in heat transfer as compared to simple two phase flow.
