The research focuses on improving the heat transfer performance of a shell-and-tube heat exchanger by modifying the baffle design. This experimental work examines how different baffle layouts affect the heat exchanger's pressure drop and thermal performance at various mass flow rates. The experimental setup included stainless-steel baffle plates with three different cut percentages (15%, 25%, and 35%) to evaluate their effects on heat transfer rates under counterflow and parallel flow conditions. The findings indicate that heat transfer rates increase with higher mass flow rates across all baffle cuts. According to the experimental results, the 25% baffle cut demonstrates the best heat transfer performance. Furthermore, the analysis shows that single-segmental baffles with a helical configuration are more effective in enhancing heat exchanger performance, particularly in high-pressure environments. These findings present new opportunities for optimizing industrial heat exchanger designs in applications such as chemical processing, power generation, and renewable energy systems.
