Experimental Correlations and Thermal Performance Study for Wavy Fin Aluminium Plate Fin Heat Exchanger

摘要

Experimental studiy about the thermal hydraulic performance of the aluminum wavy fin in plate fin heat exchanger were performed. A series of test were conduct for 16 wavy fin samples with different geometry parameters based on the DOE method. The experimental correlation equations of the wavy fin about the heat transfer and pressure drop are setup using the multiple regression method. To optimization the wavy fin geomerry parameters, the parametric study on the performance of the wavy fins is carried using the Taguchi method. The study results show the ratio of the wavy fin amplitude and wavy length is the most important factor which affacts the overall thermal hydraulic performance.
