Effect of Inner Body Shapes on Natural Convection in Square Enclosures

This review focuses on the effects of inner body shapes on magnetohydrodynamic (MHD) natural convection heat transfer within square enclosures, summarizing advancements from 2015 to 2024 and identifying future research directions. The influence of different geometric shapes such as circular, square, triangular, and elliptical on heat transfer performance and flow behavior is critically examined. The review also addresses the roles of Rayleigh and Hartmann numbers in modulating convection characteristics in the presence of a magnetic field. Key trends and findings are highlighted, along with observed research gaps, to guide future studies aiming to enhance thermal management in MHD driven systems.
