| Abstract: | Based on Nusselt's theory, a three-dimensional coordinates model was built to deal with condensation heat transfer on the side of the fin. With the model, the condensation heat transfer mechanism on the side of the fin was analyzed. As a result, an integral expression was obtained to calculate the condensation heat transfer coefficient of a single horizontal tube with annular fins. The results were compared with that of conventional solution. |
