CFD ANALYSIS FOR FLOW AND TEMPERATURE DISTRIBUTION IN SHELL AND TUBE HEAT EXCHANGER WITH BAFFLES

Shell-and-tube heat exchanger is one of the most widely used heat exchange apparatus in various industrial processes and in research fronts. Baffle selection is critical to control and improve the thermo-hydraulic performance of this type of heat exchanger. three-dimensional computational fluid dynamics (CFD) Analysis, using the commercial software, have been performed to study and compare the Temperature, heat transfer coefficient Velocity pressure distribution between the segmental baffles and helical baffles at low shell side flow rates. In this comparison, the whole heat exchangers consisting of the shell, tubes, and baffles are modelled. The model predicts the thermo-hydraulic performance with a considerably good accuracy, by comparing with Segmental baffle and helical baffle with 5 turns and 6 turns. The model is created using the commercial software and the heat transfer analysis is carried out using the fluent therefore the obtained results is then compared using the nanofluid Al2O3 in shell side
