【摘要】 随着现代工业的迅速发展,工业产品以环境污染物的形式在土壤等多孔介质中的迁移过程得到了人们的关注。出于室内物理模拟实验条件上的局限性,对这一过程的数值模拟研究也因此在污染物系统分析中起到了重要的作用。本文以污染物溶质在多孔介质中的迁移模拟理论为基础,综述了国内外多孔介质中污染物溶质的常用迁移模型研究成果,详细描述了传统的对流-弥散方程模型及其发展情况。同时综述了随机迁移模型及其它适用的迁移模型,讨论了各类模型的适用范围优势及其不足之处。最后还从多个角度指出了多孔介质中污染物溶质迁移模拟有必要注意的问题及可能的发展趋势,为后续的研究指明了方向。更多还原

【Abstract】 On the bases of simulation theory for pollutant solute migration in porous media,this paper provides an overview on the research results for migration of pollutant solute in porous media with conventional migration models.The traditional convective-dispersion equation model and its development are described in detail.The stochastic migration model and other applicable transfer models are also introduced.The applicable scopes,advantages and disadvantages of these models are discussed.Finally,problems that needs to be concerned and possible development trends for future simulation study are suggested.更多还原
