填料塔液泛气速计算公式的评选

SELECTION OF CORRELATIONS ON THE FLOODING VELOCITY IN PACKED TOWER

液泛气速是填料塔设计的重要参数，是确定塔径的主要依据。文中以国内外文献发表的６种液泛气速计算公式的计算值与国产填料液泛气速实测值进行比较，评选出适用于国产乱堆填料液泛气速的计算模型，以用于填料塔设计电算程序。

The flooding velocity is an important parameter which is also a base to calculate diame-ter in the design of packed towers.The calculated values by using six formulas from the lit-erature published in China and abroad for calculating the flooding velocity were comparedwith the experimental measurements on Chinese radOm packings. The models adapting toChinese packing for the program of packed tower design have been selected.
