摘　　要：通过多尺度方法,对HSX填料进行计算流体力学(CFD)模拟,得到了局部平均液膜厚度、气液有效润湿面积及全塔压降等数据。其中,通过建立二维和三维流体体积(VOF)两相流模型,分别计算了不同气液速度对液膜厚度及有效接触面积的影响。最终模拟压降结果与实验结果吻合性较高,表明CFD可以作为设计、改良填料的有效工具。A multi-scale computational fluid dynamic（ CFD） model has been employed to characterize the hydrodynamic performance of HSX packings. The 2D volume of fluid（ VOF） model was used to trace the gas-liquid interface and to calculate the liquid film thickness for two-phase flow; the 3D VOF model was used to calculate the effective wetting area. Finally,a 3D porous media model was proposed to calculate the pressure drop at the column scale. The simulated results were in agreement with the experimental data. The multi-scale CFD model can be used effectively to design and optimize complex structured packings.
