Abstract
This study delves into the numerical exploration of the MagnetoHydroDynamic (MHD) characteristics of an Fe3O4-Water nanofluid contained within a chamfered square enclosure under the influence of an external magnetic field. The enclosure, characterized by distinct hot and cold imposed temperatures on its side walls, features both straight and chamfered sections. The orientation of magnetic field lines was manipulated by varying the angular placement of the magnetic source. The computational framework for nanofluid dynamics is mathematically formalized through a dimensionless formulation of the Navier-Stokes equations derived from their dimensional counterparts. A comprehensive numerical analysis was conducted employing the Finite Element (FE) method, a. The interaction between the Hartmann number and the angular placement of the magnetic source was analyzed, with a specific focus on nanofluid isotherms, temperature profiles, and velocity magnitude distributions. The results were thoroughly investigated and extensively discussed.
