HEAT TRANSFER ASSESSMENT USING TAPERED PERFORATED PIN FINS

The experimental study of forced convective heat transfer on staggered pin fin arrays in a rectangular channel to quantify their heat transfer characteristics. System performances are compared between solid and various perforated pin fin heat sinks. It was found that the pin fin array performed better than solid fins and Nusselt number increased with the perforated fins. It was found that the maximum system performance is obtained with perforated pin fins when the number of perforations and perforation diameter are optimized. With the present configuration of pin fins, N = 5 and Dp = 3 mm, pin fins offer the best performance.
