摘要

管翅式换热器在析湿工况下会在翅片间形成大量液桥，液桥体积会影响换热器中冷凝水的排出。提出一种将液面弯曲线沿液桥三相接触线积分的方法计算竖直翅片间液桥体积，其中液桥三相接触线采用椭圆方程描述，液面弯曲线模型基于Young-Laplace方程的计算结果拟合得到。通过液桥三相接触线与液面弯曲线观测实验对提出的液桥体积计算模型进行了验证，结果表明，95%的计算结果与实验的误差范围在±15%内，平均误差为7.12%。

Abstract

When a fin-and-tube heat exchanger worked as dehumidifier

lots of water bridges would form between vertical fins and the water volume of these bridges could affect discharge of water condensate. A model for the calculation of water bridge volume was established by integration of meniscus curve along triple contact line of the water bridge. An ellipse equation was used to simulate the triple contact line while a model of meniscus curve at the water-air interface was obtained from calculation results of the Young-Laplace equation. The model for calculating water bridge volume was validated by experimental study on triple contact lines and meniscus curves. The model predicted water volumes of these bridges 95% times aligned with the experimental data within the deviation limit of ±15%

which had a mean deviation of 7.12%.
