| This study explores the effects of fin cross-sectional geometry on the thermal and hydraulic performance of a pin fin heat sink under turbulent flow conditions. The heat sink design features a base plate measuring 100 mm wide, 100 mm long and 3 mm high with 14 fins arranged in a 4-3-4-3 configuration, utilizing air as the working fluid. The investigation employs CFD simulations to analyze variations in heat sink performance due to different fin geometries, including circular and elliptical cross-sections with and without perforations. Results indicate that elliptical fins, particularly those with a radius ratio of 0.50, significantly enhance heat transfer rates, achieving improvements in the HTPF of up to 90% compared to traditional circular designs. The study highlights a clear correlation between increasing Re and the Nu, demonstrating the effectiveness of elliptical fins in turbulent flow conditions. However, while perforated ... |
