摘要:

本文研究了纤维状多孔材料在低液体饱和度下的毛细输运问题。研究表明,液体在这种类型的多孔材料中在低饱和度下的扩散过程可以用与之前在颗粒多孔材料中的实验和模拟中确定的类似的超快、非线性扩散模型进行宏观描述。介质。宏观扩散模型得到了使用微观网络模型模拟的支持。理论结果进行了定性比较与现有的实验观察持久性液体。

英文摘要:

The problem of capillary transport in fibrous porous materials at low levels of liquid saturation has been addressed. It has been demonstrated, that the process of liquid spreading in this type of porous materials at low saturation can be described macroscopically by a similar super-fast, non-linear diffusion model as that, which had been previously identified in experiments and simulations in particulate porous media. The macroscopic diffusion model has been underpinned by simulations using a microscopic network model. The theoretical results have been qualitatively compared with available experimental observations using persistent liquids.
