Abstract: (493 Views)
In this study, a shell and tube heat exchanger was numerically analyzed using Ansys-Fluent 15.0, a computational fluid dynamics software. Due to their high efficiency, Shell and tube heat exchangers play a significant role in industrial processes. This investigation is concentrated on the effect of two important geometrical entities, baffle height and angle, on heat transfer and fluid flow properties. Precise geometrical modeling of the device and conducting grid-independent and convergent simulations have been of primary steps of this study. The results of these simulations have been compared and evaluated using authentic papers, which showed great compatibility of these results with those of theories. It has been shown that a baffle angle of 30 degrees and a baffle with a cut height of 25% is the most efficient setup. This setup yields better heat transfer and less pressure drop finally resulting in improved thermal efficiency and moderated energy consumption of shell and tube heat exchanger systems. Overall, the results of this investigation show that by employing numerical simulation, more efficient designs are possible for heat exchangers, which will be accompanied by reduced operational costs and improved efficiency in industrial systems
