ABSTRACT: This study focuses on the analysis of extended surfaces, which are commonly employed in various engineering applications to enhance convection heat transfer. The objective is to effectively increase the heat transfer rate by introducing perforations into the lateral surface of the fins. By determining the optimal perforation design and shape for these fins, this research aids in selecting the most suitable configuration. In preparation for the examination, aluminum and copper fins are specifically selected because of their elevated thermal conductivities and extensive use in heat transfer applications. The choice is based on their respective thermal conductivities: aluminum has a thermal conductivity of 210W/mK, while copper boasts a higher thermal conductivity of 410W/mK.

KEY WORDS: Heat Transfer (HT), Heat Transfer Coefficient (HTC), Fins, Temperature and Perforations.
