摘要:

本文探究一种描述多孔介质的方法,将多孔介质的孔隙部分简化为由节点和管道组成的拓扑网络模型,模拟水和空气两相在介质中的渗流过程,得到流动稳定时介质中两相的分布图形,并计算出水能够透过整个介质的概率。



Abstract:

This paper investigates a method to describing the porous medium, which is simplifying the pore part of porous medium into network structure model consist of node and pipeline. We simulate seepage flow of water and air in porous medium through this model, obtain the figures of gas-liquid distribution when steady, and cipher out the probability of that water flows through the whole medium.
