Abstract
This study investigates the thermal and hydrodynamic performance of a tubular heat exchanger equipped with internal baffles of different geometries. Numerical simulations were conducted to evaluate the influence of key operating parameters, including fluid temperature (313 K, 333 K, and 353 K) and Reynolds number. The results show that increasing the fluid temperature enhances heat transfer due to the larger temperature gradient between the fluid and the wall. Similarly, higher Reynolds numbers promote stronger flow turbulence, leading to significant disruption of the thermal boundary layer and improved heat transfer performance. The performance factor increases from 1.51% to 2.26% as the Reynolds number rises from 30 to 50, confirming its major effect on thermal enhancement. Furthermore, the analysis of baffle geometries reveals that Configuration No. 1 provides the best performance, offering an optimal balance between heat transfer enhancement and pressure drop. Overall, the study demonstrates that combining higher fluid temperature, increased Reynolds number, and an optimized baffle design effectively improves the thermal efficiency of heat exchangers.
