Parametric Study and Performance Analysis of Shell and Tube Heat Exchanger

Abstract
Enhancement of heat transfer through shell and tube exchangers stills taking high attention by researchers. The present work investigated the effect of shell diameter and tube length on heat transfer coefficient and pressure drop for shell side with both triangular and square pitches. In addition, the effect of baffle spacing and cutting space on heat transfer coefficient and pressure drop were studied. Moreover, standards fouling rates used for both shell and tube sides to estimate the reduced heat transfer. Increasing shell diameter with a triangular pitch and pull-through floating head recorded 3% increasing in heat transfer coefficient for increasing in shell diameter. While increase in heat transfer coefficient for shell side by increasing in shell diameter with split-ring floating head and square pitch. Heat transfer coefficient for shell side reduced by increasing baffle space from shell diameter and the pressure drop. Increasing cutting space from 15% to 25% decreases heat transfer coefficient and the pressure drop diminished. Increasing tube length leads to enhance the heat transfer coefficient and pressure drop for tube side. For shell side, increasing tube length gives increasing in heat transfer coefficient and increasing for pressure drop. Fouling resistance change on shell side shows a high effect on heat transfer more than same rate change on the tube side. Based on the result, this study can help designers to quick understand of each parameter effect on heat transfer into shell and tube exchangers.
