This project delves into the realm of heat exchangers and passive heat enhancement techniques. Heat exchangers are critical components in various industries, facilitating efficient thermal energy transfer. Passive techniques, such as twisted tape inserts, offer innovative ways to bolster their performance. Using a validated model in ANSYS software, we conducted a comprehensive analysis of heat exchanger efficiency, taking a stepwise approach. We initiated our study by examining the baseline heat exchanger, devoid of any enhancements, followed by the introduction of twisted tape inserts. We progressively increased the twists from 2 to 4 and integrated hole patterns. The outcomes were striking, showcasing a significant 13.104 K reduction in hot water outlet temperature with the implementation of twisted tape and holes. Furthermore, the performance of the heat exchanger increased by 3.96% with these heat enhancement techniques. These results emphasize the efficacy of inventive enhancements in optimizing heat exchanger designs, promising energy conservation, and heightened system performance within industrial heat transfer processes.
