In this study, air-side performance of wave fin-and-tube heat exchangers having large diameter(12.7mm, 15.9mm) tubes was investigated. Eight samples having different tube rows were tested. For both configurations, the effect of tube row on j-factor was negligible. However, f-factor increased as the tube row decreased. The j-factor and f-factor of the tube diameter 12.7mm sample were approximately 32% and 26% higher than those of 15.9 mm sample.
