板网填料液泛研究

A STUDY ON FLOODING IN COLUMNS CONTAINING STRUCTURED PACKING

将用于在管两相流动的Wallis'方程根据规整填料的结构特征加以改进，周末关联规整填料的泛点数据，计算结果与板网填料的泛点实验数据相差很小。将该方程重新整理可以反映规整填料泛点能力参数和流动参数的关系，计算结果与实验值相当。因此该方程大一种比常用的Bian－Hoagen关联式更好的关联规整填料泛点的方法。

This paper uses Wallis' equation for two-phase countercurrent to correlate the flooding point data. The predicted effects of the geometric variables of the packing on nooding are confirmed by experimental data.The resulting Muation which describes nooding can be rearranged to give nooding lines on a skerwood-type plot for columns containing structured packing. This Wallis-type model is a better way to correlate structured parking fiooding data than the more usual Bian-Hoagen model for pasked columns;
