对矩形通道、多孔扩散层以及两者结合的传质过程进行了分析。详细计算的结果，并在作为吹参数和几何形状的函数的传质驱动力方面相关，其特征在于由纵横比和堵塞因子。结果表明，一个简单的解决方案，总的驱动力可以得到共轭传质问题。这种解决方案在性质上是相当普遍的。数学基础与用于获得结果的计算过程的细节一起被呈现。版权所有© 2005由加拿大国家研究理事会
An analysis is performed for mass transfer in a rectangular gas passage, porous diffusion layer, and the combination of the two. The results of detailed calculations are presented and correlated in terms of the mass transfer driving force as a function of the blowing parameter and geometry, as characterized by the aspect ratio and blockage factor. It is shown that a simple solution for the overall driving force may be obtained for the conjugate mass transfer problem. This solution is quite general in its nature. The mathematical foundations are presented together with the details of the computational procedure used to obtain the results.Copyright © 2005 by National Research Council of Canada
