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 the cylindrical coordinate system, an axisymmetric two-dimensional heterogeneous mass transfer model describing the dispersion of the second liquid-phase enhanced gas-liquid mass transfer was established. The axial and radial distributions of the mass transfer components in the liquid film were calculated by the finite difference method Concentration distribution and mass transfer enhancement factor, the calculation method is fast and effective, and can well fit the experimental data in the existing literature.
