RIA: Structural Permeability Tensor of Reconstructed Porous Soil Media

本研究的目的是开发一种基于模拟的新技术，旨在建立真实多孔介质的模型。基于在微观结构水平上使用多孔介质薄片进行的特性测量，将创建一种与原始介质具有相同平均几何特性的人工介质。通过对三维重构土介质样品的场方程进行数值求解，得到渗透张量。计算结果将与实验数据进行比较。通过在薄片上直接观察来确定渗透率张量的可能性也将被研究。＊＊＊

9309345 Muhunthan The objective of this research is to develop a new technique based on simulation, aimed at building models of real porous media. On the basis of measurements of characteristics made using thin sections of porous media at the microstructural level, an artificial medium that has the same average geometric properties as the original medium will be created. The permeability tensor will be obtained by solving the field equation numerically in a sample of three-dimensional reconstructed soil medium. the results will be compared with experimental data. The possibility of determing the permeability tensor by direct observations on thin sections will be also investigated. ***
