摘　　要：对纯净饱和蒸气沿水平圆管外轴向强制对流凝结换热的强化传热机理进行了分析和计算，得到了适用该种流动形式的强化传热措施．计算表明这种措施强化了凝结传热．通过对液膜的受力分析，得出了较佳槽宽的计算公式，为工程设计及制造提供依据．The mechanism analysis of enhancement heat transfer of the forced convective condensation of the saturated steam flowing axially outside the horizontal tube is conducted, and the measure to enhance the heat transfer of this kind of flow is achieved. The calculation result indicates that the measure enhances the convective condensation heat transfer. This paper also presents a formula to optimize groove width, which provides important basis for engineering design and production.
