摘要
多孔介质广泛存在于地下岩土结构、工程材料、生物体中,由于多孔介质微结构的复杂性,多孔介质渗流问题受到广泛关注。总结介绍了多孔介质渗流理论在国内外的研究现状,对多孔介质的描述、渗流问题的研究方法以及多孔介质中溶质运移、热量运移以及数值模型等方面的研究进展作了评述,并就多孔介质渗流理论在环境、农业、生态等领域的应用与发展方向提出看法。
Porous media are widely distributed in nature, and include underground rock, soil, engineering materials, and organisms. The seepage problems of porous media are of concern because of their microstructural complexity. This paper summarizes the status of research into porous media seepage theory, and discusses the descriptions of porous media, the research methods used to investigate seepage problems, the transportation of solutes in porous media, heat migration in porous media, and research approaches such as numerical modeling. Finally, the paper offers thoughts about the application of porous media seepage theory to developments in various fields, including those of the environment, agriculture, and ecology.
