The Impact of a Non-Uniform Magnetic Field on Mixed Convection in a Lid-Driven Cavity Filled with Fe₃O₄/Water Nanofluid

Abstract

Research on Fe3O4/water nano liquid in a lid-driven chamber under mixed convection conditions has been carried out with a focus on the impact of a non-uniform magnetic field on the heat exchange process. The governing equations were resolved using the finite-volume-method-based in-house solver. Several parameters were considered in the analysis, including the magnetic number and the Reynolds number. According to the primary findings, the existence of a magnetic field (MF) generates a region of recirculation near the magnetic source, resulting in improved local heat exchange. Moreover, the effectiveness of the magnetic field is greater at lower Richardson numbers, and the buoyancy force diminishes the influence of the magnetic source.
