Description: Heat transfer performance of horizontal, integral-fm tubes made of copper, aluminum, copper-nickel, and stainless steel was evaluated using a boiler and steam condenser assembly. Testing was done at vacuum and atmospheric pressure conditions. The tubes tested had an inner diameter of 12.7mm, a root diameter of 13.88mm, and fin heights ranging from 0.5mm to 1.5mm, in 0.25mm increments. The outside heat transfer coefficient was determined first by finding the overall heat transfer coefficient, Uo, then by using the Modified Wilson Plot Technique. The results indicated that the performance of a finned tube is very dependent on fin height and tube material. Moreover, the results were compared with the predictive models of Beatty and Katz, Rose, Adamek and Webb, and Honda et al., with a modified version of the Rose model demonstrating the best predictive capabilities.
