Improved Shell and Tube Heat Exchanger (STHX) Customized using a variety of Baffle Arrangements

Thermal performance and pressure drop are important aspects to consider when evaluating a shell and tube heat exchanger. Thermal performance and pressure drop are both affected by the direction of fluid flow and the types of baffles used in different orientations. Increasing the intricacy of baffles improves heat transfer while simultaneously increasing pressure loss, which necessitates more pumping power. This affects the efficiency of the system. The numerical simulations on diverse baffles, such as single segmental, double segmental, and helical baffles, are presented in this thesis. The effect of baffles on pressure drop in a shell and tube heat exchanger is seen here. Single segmental baffles demonstrate the establishment of dead zones when heat transport is impeded. When compared to single segmental baffles, double segmental baffles reduce vibrational damage. Because dead zones are eliminated when helical baffles are used, pressure drop is reduced. Heat transfer is improved when there are fewer dead zones. Smaller pumping power is required as a result of the lower pressure drop, which improves overall system efficiency. The results reveal that helical baffles are superior to the other two types of baffles.
