Summary

In this study, 28 heat exchanger samples were tested in an open circuit thermal wind tunnel over a velocity range of 1 to 20 m/s for a number of geometries. The geometrical variations include the number of tube rows, fin thickness and the spacing between fins, rows and tubes. It was found that the fin type affects the heat transfer and friction factor, and that the number of tube rows has a negligible effect on the friction factor. The number of tube rows effect was found to be influenced by the fin and tube geometries as well as the Reynolds number.
