摘要: | A comprehensive study to investigate the heat transfer and friction characteristics of convex-louver and wavy fin-and-tube heat exchangers was carried out in this study. A total of 14 samples of heat exchangers, including seven convex-louver and seven wavy fin samples having identical waffle heights, were tested and compared in the present investigation. The effects of the number of tube row and fin pitch on the thermal-hydraulic characteristics were also reported. Results were presented as plots of Fanning friction factor f and the Colburn j factor against a Reynolds number based on a tube collar diameter in the range of 3 x 10(2) to 8 x 10(3). |
