This article explores the significance of Shell and Tube Heat Exchangers (STHX), with a focus on various baffle
types such as Segmental, Double segmental, Helical, Disc-and-Doughnut, Clamping anti-vibration, and Flower-B.
In this study, the commercial software ANSYS FLUENT is used to simulate the problem. The study evaluates their
impact on heat exchanger performance using parameters like overall heat transfer coefficient (OHT), pressure
drop (PD), and Performance Evaluation Criteria (PEC). Clamping anti-vibration, Flower-B, Helical, and Double
segmental baffles exhibit reductions in shell side PD by 14%-28%. Despite OHT reductions in these designs, Discand-
Doughnut baffles demonstrate a higher OHT (21%-24%) compared to Segmental baffles. Based on PEC
values, Disc-and-Doughnut baffles are identified as the most favorable. Further investigation into different
numbers of Disc-and-Doughnut baffles reveals increased OHT (17%-29%), PD (58%-59%), and cold water
temperature (0.5%-1%). The STHX with Disc-and-Doughnut 10 baffles displays the highest PEC value, establishing
it as the most effective STHX in the simulation.
