Abstract

The heat performance of the elliptical tube perforated fins heat exchanger was investigated with numerical simulation methods in comparison with that of the circular tube plain fins exchanger. Based on the analysis of heat transfer rate, Colburn factor j, pressure drop, friction factor f of the air side of the fin, and the comprehensive performance index \(j/f^{1/3}\), the performance of the elliptical tube perforated fin is better than that of the circular tube plain fin. When the air flow velocities range between 1 and 4 m/s, the heat transfer factor j of the elliptical tube perforated fin is higher than that of the circular tube plain fins by 7.1–15.3%, while the pressure drop of the elliptical tube exchanger reduces by 30.1–36.6%, and the comprehensive performance index \(j/f^{1/3}\) is higher than that of the circular tube plain fin by mean 18%. The maximum rate is near 31.9%, which indicates that the performance of the elliptical tube perforated fin is better than that of the circular tube plain fin.
