摘要

给出了发生多尺度流动的具有双同心圆柱孔的微/纳米多孔过滤膜的优化参数值的多尺度计算结果。对于较弱的液体-孔壁相互作用,较大孔隙的半径与较小孔隙(即过滤孔隙)的半径的最佳比率可以根据经典方程计算,然而,当吸附层的厚度与较小孔隙的半径的比值Landax大于0.1时,由于吸附层效应,膜的相应最低流动阻力仍然应该根据多尺度分析来计算。对于中等和强烈的液体-孔壁相互作用,应通过多尺度分析计算孔径的最佳比率,并且膜的相应最低流动阻力远高于经典计算,表明当Landax>=0.1时吸附层的显著影响。

Multiscale Analysis of the Performance of Micro/nano Porous Filtration Membranes with Double Concentric Cylindrical Pores: Part II-Optimization Results
The multiscale calculation results for the values of the optimized parameters are presented for the micro/nano porous filtration membranes with double concentric cylindrical pores where multiscale flows occur. For a weak liquid-pore wall interaction, the optimum ratio of the radius of the bigger pore to the radius of the smaller pore (i.e. the filtration pore) can be calculated from the classical equation, however the corresponding lowest flow resistance of the membrane should still be calculated from the multiscale analysis owing to the adsorbed layer effect when the ratio Landax of the thickness of the adsorbed layer to the radius of the smaller pore is greater than 0.1. For medium and strong liquid-pore wall interactions, the optimum ratios of the pore radii should be calculated from the multiscale analysis, and the corresponding lowest flow resistances of the membrane are much higher than the classical calculation showing the significant effect of the adsorbed layer when Landax>=0.1.
