Abstract: Developing high-efficiency heat exchanging equipment such as heat exchangers and solar air heaters is an effective way to conserve energy. In order to achieve this objective, fins can be introduced on the internal surface of heat exchangers. For higher efficiency the surface area of contact of these fins has to be increased. So, Perforations like circular holes are also introduced in these internal fins to get higher efficiency. Different arrangement configurations like Parallel oriented (P type) and collinearly oriented (V type) with different materials such as Aluminium and Brass with and without perforations different velocities are investigated and found to have different heat transfer characteristics. From this study the optimum orientation, material and profile of the fin is identified for better heat transfer characteristics.
