Experimentation & CFD analysis of intercooler fins in two stage reciprocating air compressor

Abstract

This paper shows comparison of Aluminum and Copper fin tube intercooler used in multistage reciprocating air compressor. Results are validated with ANSYS – Fluent-18.2 software. The experimentation is done on the Copper fin tube length 1090mm with helically wounded strip width of 6mm and 8 numbers of fins per inch. Volumetric efficiency increases and work input decreases for Copper fin tube with air velocity of 5 m/s. The results shown increase in heat transfer with decreasing air temperature.
