This project aims to develop an efficient multi-scale laboratory-based modelling framework for colloidal suspensions flow in porous media by utilizing recent advances in 3D/4D image-based geometrical/topological analysis. Regional partitioning techniques based on local structural measures are used to observe the penetration/retention of colloids into identified zones. Zone-dependent colloid interaction probabilities for computational modelling are derived from fundamental relationships. Expected outcomes of this project include a full-scale modelling capability for heterogeneous samples validated by experiment and the extraction of robust model coefficients for newly developed theory for colloid-suspension transport through porous media.

该项目旨在开发一个有效的多尺度实验室为基础的建模框架，通过利用最新的进展，在3D/4D图像为基础的几何/拓扑分析的胶体悬浮液在多孔介质中的流动。基于局部结构措施的区域划分技术用于观察胶体渗透/保留到识别区。区域相关的胶体相互作用的概率计算建模来自基本关系。该项目的预期成果包括通过实验验证的异质样品的全面建模能力，以及为新开发的胶体悬浮液通过多孔介质迁移理论提取稳健的模型系数。
