Corrugated tubes are increasingly becoming more fascinating techniques for acquiring higher efficiency in heat exchangers to minimise costs. Hence, a 1 mm thick aluminum tube of six ̶ start spiral corrugations and one smooth tube were modeled using configurations based on Ansys software package. In this study, the effects of geometric parameters on the heat transfer characteristic are investigated and optimized for the best overall thermal-hydraulic performance using Taguchi method. It is found that corrugation height have dominant influence on heat transfer characteristic with contribution ratios of 74.79% respectively while corrugation pitch has minor effects. As far as pressure drop and flow friction characteristic is concerned, corrugation height have also dominant influence on pressure drop and flow friction characteristic with contribution ratios of 71.24% and 65.12% respectively while corrugation pitch has minor effects. The optimal combination for SNR-TPC is determined as A3B2.
