Heat Transfer Enhancement Through Perforated Fin

Abstract

Enhancement of heat transfer rate and reduction of fin dimension has major criteria in designing of heat exchanger components. This project is an experimental analysis to investigate forced heat transfer of rectangular fin by comparing both solid and circular perforation along the lateral axis of the fin. Performance is analyzed experimentally by designing experimental setup for specific fin length. Thermal performance, effectiveness and pressure drop reduction. Due to increase in surface area or convective area heat transfer rate increases, pressure drop reduces, Nusselt Number increases. The large impact is that higher reduction in weight of fin is achieved by producing perforation which is the major requirement in heat transfer equipment.
