Abstract

Experimental and numerical studies were conducted for different fin shapes (solid fins, serrated fins-8 wings, serrated fins-11 wings, and serrated fins-14 wings) and spacing of shell and helically coiled heat exchanger. Investigations were made on the heat exchanger's fin spacing. The FLUENT 19 numerical code was used to illustrate the thermofluid behaviors through the shell and finned tubes heat exchanger. Using an inlet hot water temperature of 80 oC for the coil side and inlet cold water temperature of 10 oC for the shell side, mass flow rates along the sides of the coil and shell were 0.05-0.2 kg/s. The impact of fin shape on temperature distribution was clear. The use of solid fin results raised Nussult number than serrated fins-8wings, serrated fins-11wings, and serrated fins-14wings with an increase of around 6.3%, 9.5%, and 12.6%, respectively, and in the case without fins about 17.8% for the same value of Dean number=6000.
