This study carries out a detailed CFD analysis of a concentric triple-tube heat exchanger to investigate the thermal performance for different configurations and nanofluid concentrations of 0.0% and 0.1%. The investigation covers heat transfer rates, temperature distributions, and fluid flow dynamics in three different setups: baffle-less operation, straight baffles, and baffles inclined at 45°. Parameters analyzed are the inlet and outlet temperatures, specific heat, and the overall heat transfer coefficient for system efficiency. The results indicated that nanofluid concentration played a critical role in thermal performance. With a 0.1% concentration, heat transfer efficiency is highly improved. In configurations, the inclined baffle at 45° angle yields the highest thermal efficiency because temperature gradients are optimized, and fluid turbulence is increased. The results of this study have the potential for advanced baffle designs and nanofluids in efficient heat exchanger performance. This study has provided valuable insight into the optimization of heat exchanger designs to improve energy efficiency in industrial applications. Future research can further explore additional nanofluid types and advanced geometrical modifications to further enhance performance.Downloads
