Abstract:
Shell-and-tube heat exchangers are widely used in chemical, power, and process industries due to their robustness and suitability for high-pressure and high-temperature applications. Among the various design parameters, baffle configuration plays a critical role in enhancing shell-side heat transfer by inducing turbulence, while simultaneously affecting pressure drop. In this study, the thermal and hydraulic performance of a shell-and-tube heat exchanger with different baffle configurations—single baffle, double baffle, and inclined double baffles at 10° and 20°—is numerically investigated. Three-dimensional computational fluid dynamics (CFD) simulations are carried out using ANSYS Fluent to analyze flow behaviour, temperature distribution, pressure drop, and velocity fields on the shell side.
