9309345 Muhunthan本研究的目的是开发一种基于模拟的新技术，旨在建立真实的多孔介质模型。 在使用多孔介质的薄片在微观结构水平上进行的特性测量的基础上，将创建具有与原始介质相同的平均几何特性的人工介质。 渗透率张量将通过在三维重建土壤介质样本中数值求解场方程来获得。 将结果与实验数据进行比较。 还将研究通过对薄片的直接观察来确定渗透率张量的可能性。 ***

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. ***
