摘要
以Nusselt理论为基础,运用三维坐标建立了肋片侧面的冷凝传热模型,对肋片侧面的冷凝传热机理进行了分析,得出了肋片侧面表面传热系数的积分表达式。利用此法对水平环肋单管表面传热系数进行计算并将结果与传统解法进行比较。
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.
