摘要 直观的了解翅片管的翅片侧壁上的凝结液的分布和流动情况对深入理解翅片管上的对流冷凝传热机理和翅片管上的液膜理论计算具有重要意义。主要针对含湿混合气体在水平单翅片管管外的对流冷凝传热进行了可视化实验研究;并利用相关图像处理软件对翅片侧壁上的凝结液滴直径大小进行了测量统计。通过对实验数据的分析,得到了翅片管的翅片侧壁凝结液的分布和流动规律。 It is significant to know the distribution and flow of condensate on the fin surface directly for comprehending the mechanism of condensation and the calculation of liquid film.Visualization experiment of condensation over a horizontal fin tube is performed.Based on the measurements,the diameter of the condensate drop on the fin surface was measured by image processing software.The law of distribution and flow of condensate drop was obtained.
