摘要 A new device of double-pass mass exchanger under asymmetric wall concentrations is to divide a parallel-plate channel by inserting a permeable barrier into two subchannels. The adjustment of the ratio of wall concentrations and the recycle effect was introduced to analyze the improvement of mass transfer efficiency in double-pass devices under asymmetric wall concentrations. The theoretical formulation of such conjugated Graetz problems were developed and the analytical solutions were obtained by using the separation of variables and superposition method. The theoretical predictions of the double-pass mass exchanger with external recycle were compared with those in single-pass devices under the same working dimensions. The average outlet concentration distribution and mass-transfer efficiency improvement were represented graphically with mass-transfer Graetz number and permeable membrane location as parameters. The effects of the membrane parameter and recycle ratio are also discussed in this study.
