| 摘 要： | 基于多孔介质两相流模型,编制了相关的有限元计算软件,对已有文献中关于重非水相流体(Dense Non-aque-ous Phase Liquids,DNAPL)在饱和多孔介质中迁移的离心模型试验进行了模拟,探讨了DNAPL的重度与粘滞度等参数对其在地下水位线下迁移规律的影响,并对DNAPL在均质以及非均质地层的迁移进行了模拟,计算结果对DNAPL在饱和多孔介质中的迁移过程、影响范围的描述以及评价有一定的参考意义。

| Abstract: | Based on two-phase flow model for porous media,a finite element code was develop,and a centrifuge model test concerned about the transferring of Dense Non-aqueous Phase Liquids(DNAPL) in the saturated porous media was simulated.The effect of viscosity,density of DNAPL on the discipline of its transferring below the underground water level was discussed.The numerical analysis of DNAPL transfer in homogeneous and heterogeneous strata was carried out.The results have some referenced significance for describing... |
