摘要

在纳米孔过滤膜中，当过滤孔半径较大，吸附层在孔壁上的流动与孔中心区域连续流体的流动相当时，需要对膜的性能进行多尺度分析。本文对具有双同心圆柱孔的纳米孔过滤膜的性能进行了多尺度分析。在不同的操作参数值下，计算了弱流体-孔壁相互作用下膜的无因次流动阻力。结果表明，滤孔半径与另一个较大孔半径的最佳比值可使膜通量达到最高。

Multiscale Analysis of the Performance of Micro/nano Porous Filtration Membranes with Double Concentric Cylindrical Pores: Part I-Analysis Development

In nanoporous filtration membranes, when the radius of the filtration pore is so big that the flow of the adsorbed layer on the pore wall is comparable with the flow of the continuum fluid in the central region of the pore, the multiscale analysis is required for estimating the performance of the membranes. The present paper presents such a multiscale analysis for the performance of nanoporous filtration membranes with double concentric cylindrical pores. The dimensionless flow resistance of the membrane was calculated for a weak fluid-pore wall interaction for varying operational parameter values. It was found that there is the optimum ratio of the radius of the filtration pore to the radius of the other bigger pore for the highest flux of the membrane.
