Thermal management optimization in electric vehicle batteries using Fe3O4+CoFe2O4/E.G + H2O hybrid micropolar nanofluid

Abstract

This study investigates at the development of a high-efficiency refrigeration system for new lithium-ion battery packs used in electric cars, with an emphasis on critical thermal management factors including uniformity of temperatures and heat dissipation efficiency The three-dimensional flow of the Fe₃O₄ CoFe₂O₄/E.G + H₂O hybrid micropolar nanofluid is considered. The flow is modeled mathematically in partial differential equations and then transformed to the equivalent set of nonlinear ordinary differential equations using appropriate similarity transformations. These equations are numerically solved using the Matlab bvp4c module. The graphical analysis explores the importance of micro-polar factors in improving axial heat transfer and the requirement for specific magnetic field orientations to maximize thermal performance across various flow directions. Adjustments to angular velocity and porosity parameters highlight the importance of strategic cooling channel design in facilitating efficient fluid dynamics and reducing flow resistance, hence increasing cooling system efficacy. The findings also determine the issues provided by growing nonlinear radiation, heat source intensity, and temperature difference coefficients, which require strong and novel cooling methods to properly control increased heat generation and temperature sensitivity. These next-generation battery packs can achieve greater thermal control by incorporating modern cooling technologies and improving cooling system designs resulting in optimal operating temperatures and increased overall vehicle dependability and economy.
