多孔介质孔隙模型及其应用——毛细管束模型

Developement and Application of Pore Structure Model --Bundle of Capillary Tubes Model

在多孔介质中许多物理化学行为均与其自身的孔隙结构构型密切相关 ,建立一种切实可行的孔隙模型将会对研究材料和化工过程多孔介质提供很大的帮助。毛细管模型是一种较为简单的实用孔隙模型 ,它可以通过使用毛细管压对多孔介质的浸渗和排空情况进行计算 ,也可以用于对多孔介质中的浸渗和排空过程进行定性的解释。针对在研项目 。

In a porous media many physico chemical properties are highly associated with the pore structure patterns. The establishment of applicable pore models could provide much help to research these pore structure media in materials science and chemical processes. 'Bundle of Capillary Tubes Model' is relatively simpler and more practical to approach to real case, which lets quantitative calculation possible by taking account of capillary filling and emptying of the pore space as a function of the capillary pressure, or provides qualitative descriptions for the filling or emptying processes. The 'Bundle of Capillary Tubes Model' is reviewed by aiming at ongoing research topics, and some comments are made regarding this pore structure model.
