用液体沿垂直壁面的膜状流动来模拟液体在填料表面的流动，用固定床的特性参数来模拟填料层，导出求算整砌填料层和乱堆填料层最小润湿速率的数学模型.还讨论了数学模型的计算结果.This paper deals with the imitation of liquid Flowing over the surFace of packings with liquid Film Flowing over the surFace of vertical plates, and the imitation of a packed bed with characteristic parameters of a Fixed bed.Methematical models are derived For calculating minimum wetting rate of stacked packings and dumped packings, and also the calculation results obtained From these models are discussed
