Abstract :In this study, the variation of heat transfer characteristics was observed by means of plates attached to the copper tube of a counter-flow shell and tube heat exchanger designed in SolidWorks. The heat exchanger body, i.e. the shell, and the plates were defined as made of 304 stainless steel, and the thin-wall inner tube as copper. With respect to the number of plates and the positioning thereof, the outlet temperatures of the hot and cold fluids were examined and compared in terms of heat transfer. As a result of the data obtained from the analyses, the heat transfer was shown to increase linearly with the number of plates to a certain number, and the optimum number of plates was determined to be 7, having increased the heat transfer by 24% -52% compared to the case without plates. The positioning of the plates, on the other hand, found to have an insignificant effect.
