The main objective of this study is the technical optimization of a Shell-and-Tube Heat Exchanger (STHE). In order to do so, a simulation model is introduced that takes into account the related gas-phase circulation. Then, simulation verification experiments are designed in order to validate the model. The results show that the temperature field undergoes strong variations in time when an inlet wind speed of 6 m/s is considered, while the heat transfer error reaches a minimum of 5.1%. For an inlet velocity of 9 m/s, the heat transfer drops to the lowest point, while the heat transfer error reaches a maximum, i.e., 9.87%. The pressure drop increases first and then decreases with an increase in the wind speed and reaches a maximum of 819 Pa under the 9 m/s wind speed condition. Moreover, the pressure drops, and the heat transfer coefficient increases with the Reynolds number.
