摘要
从理论上分析了毛细效应发生的条件:建立了5种不同截面纤维形成毛细管的模型,推导出了不同截面纤维形成的毛细管的大小,分析了发生毛细效应的难易程度;统计了不同截面纤维根数与形成毛细管根数的关系;总结出了不同截面纤维形成毛细管液态水毛细运输的流量;从而评价了不同截面纤维的湿传导能力,提出了优化方法。
In this paper, the condition of capillary effect producing is analyzed in theory; the capillary' s models of five cross-sectional fibers are set up ,their capillary's sizes are calculated,and whether easy or not capillary effects happen in these capillaries is analyzed. According to the statistics of the number of the fibers and the capillaries the relations between the number of the fibers and the capillaries are presented; the formulas of flow rates in different cross-sectional fibers are got; at last wet permeability of different cross-section fibers is evaluated and the optimal way is presented.
