Abstract

An experimental study of the air-side thermal hydraulic performance of the aluminum wavy fin in heat exchanger was performed. A series of tests were conducted for 16 wavy fin samples with different geometry parameters. The experimental correlation equations of the wavy fin about the heat transfer and pressure drop are set up using the multiple regression method. The parametric study on the performance of the wavy fins is carried out using the Taguchi method. The study results show that the ratio of the wavy fin amplitude and wavy length is the most important factor that affects the overall thermal hydraulic performance.
