Numerical investigation of heat transfer and pressure drop in shell tube heat exchanger with double segmental baffle

In this study, a shell-and-tube type heat exchanger with double segmental baffles inside the shell is investigated by numerical simulation (CFD) methods. In the shell of the heat exchanger, the water fluid with a temperature of 300 k and a specific mass flow rate is flowing, while the tubes are held steadily at 450 K. Additionally, the baffles are located at fixed numbers, heights, and intervals. The results reveal that an increase in the mass flow rate of the water fluid within the shell leads to a direct improvement in heat transfer rates and pressure drops. In this research, for increasing the mass flow rate from 0.5 to 1, 1.5 and 2 kg/s, the heat transfer rate are increased by 79.75%, 146.03% and 215.8%, respectively, and the pressure drop are also increased by 297.47%, 827.7% and 1541.8%.
