Experiments and Numerical Investigations for Heat Transfer from a Horizontal Plate via Forced Convection Using Pin Fins with Different Hole Numbers

This study focuses on perforated pin fin convection heat transfer. study's goal is to see if fins may help transmit heat. Perforation diameter and hole count are evaluated each pin. The Nusselt number of pins 47% higher than solid pins, it increases with perforation count. Unperforated have a 19% lower pressure drop. Using circular holes as sinks, we examined forced There were perforations. They conducted in specifically designed laboratory. At low power, non-perforated lose 35 31 degrees Celsius, while only 29.8 (50 W). 55°C, unperforated hit 55°C at full 38°C (600 model had 16 was built aluminum alloy. When compared fins, found be the best way improve transfer because they 40% lighter improved thermal efficiency by 30% 85% increasing convective coefficient reducing gradient.
