摘要
介绍并分析了现有国内外文献中比较常见的几类针对管内与波纹板通道内冷凝传热与压降计算的关联式 ,指出了影响管内与波纹板通道内冷凝传热和压降性能的几个最主要的参数 ,其中冷凝全程积分平均干度是决定圆或者非圆冷凝通道压降的重要因素 ,对冷凝换热的工程设计具有指导意义。
The correlations for calculation of condensation heat transfer and pressure drop inside the circular tubes and corrugated plate channels, that are available in present publications, are introduced and analyzed. The most important factors that affect the performances of condensations heat transfer and pressure drop inside the circular tubes and corrugated plate channels are pointed out. Especially, the dependence of the pressure drop inside tubes or non-circular channels on the integrated mean content along the entire condensation path is emphasized. The results of present paper have certain instructional significance to engineering designs of the condensation heat transfer.
