摘　　要：在柱坐标系中建立了描述分散第二液相增强气液传质的轴对称二维非均相传质模型,采用有限差分法计算了传质组分在液膜区内的轴向和径向浓度分布以及传质增强因子,计算方法快捷、有效,并且能很好地吻合现有文献中的实验数据.In this paper, a new axisymmetrical two-dimensional heterogeneous mass transfer model describing gas-liquid mass transfer enhancement by a dispersed liquid phase is established in the cylindrical coordinate system. The calculation is fast and effective, and the calculated results are in fair agreement with the data available in the literature.
