Abstract

Shell and tube heat exchangers (STE) are extensively utilized in industrial applications due to their effective heat transfer capabilities. This study focuses on the influence of baffle design within an STE, analyzing different baffle configurations to optimize performance. Computational Fluid Dynamics (CFD) simulations were performed on a lab-scale STE model, evaluating the effects of baffle number, spacing, and cuts on heat transfer and pressure drop. The study considered three turbulence models: Spalart-Allmaras, k-ε standard, and k-ε realizable. Results indicated that increasing the number of baffles enhances heat transfer but also raises pressure drop. Among the tested models, the k-ε realizable model provided the best performance for complex geometries. The study concluded that a baffle cut of 50% and an optimal number of baffles significantly improve heat transfer while maintaining manageable pressure drops, with model D (12 baffles) showing the highest efficiency. These findings offer valuable insights for designing more effective and efficient shell and tube heat exchangers.
