This document presents a study on the performance of a double pipe heat exchanger with and without triangular baffles. Experiments were conducted with the heat exchanger in both parallel flow and counter flow configurations, and with varying hot and cold fluid flow rates. The results showed that heat transfer rate, log mean temperature difference (LMTD), and effectiveness were highest when triangular baffles were used compared to no baffles. This is because baffles promote better fluid mixing and heat transfer. The conclusions indicate that triangular baffles can significantly improve the performance of a double pipe heat exchanger.
