Enclosure’s inclined wall is hotter, whereas the vertical border is adiabatic and the bottom is cooler. The study aims to clarify how geometric changes affect thermal performance and offers new perspectives on how to improve heat dissipation mechanisms. A COMSOL Multiphysics version 6.2 has been used to solve numerical solutions. Streamlines and thermal distributions are examined systematically in order to understand how the unique geometry and baffle size of triangular cavities can influence the fluid flow. This influence can result in optimized flow patterns, promoting efficient heat transfer by directing the fluid to specific areas that require more cooling. In comparison with conventional designs, this optimization results in more efficient convective heat transfer, which raises cooling efficiency and lowers thermal resistance. Furthermore, by strengthening heat transfer characteristics in heat transfer systems, these geometries increase thermal efficiency, which helps several sectors, including the production of electricity, HVAC, and the automobile industry.
