纯质制冷剂沸腾换热系数的实验关联式的比较

Comparing the experiment connecting formala for local flow boiling heat transfer coeffients of pure refrigerants

利用从文献中收集到的局部沸腾换热系数的实验数据,对纯质管内沸腾换热和管外池沸腾换热系数的现有关系式的准确性以及适用范围做了比较,筛选出了与实验吻合较好的计算公式,为经济而有效的设计蒸发器提供了参考。

Based on the experiment data collected from the references, the accuracy and application range of different formulae for predicting the local in-tube boiling and pool boiling heat transfer coefficients of pure refrigerants are examined. The formula of the heat transfer coefficients in good agreement with experimental data has been selected, in order to offer a reference for economic and effective design of evaporators.
