Hilpert0207719This collaborative research proposal aims to combine high-resolution tomographic datasets with state-of-the-art pore-scale modeling techniques to investigate the flow and entrapment of nonaqueous phase liquids (NAPLs). We will focus on mixed-wettability systems and the impact of geometric descriptors and anisotropy on multiphase flow. Synchrotron microtomography stations at Center for Advanced Microstructures and Devices at Louisiana State University and the Advanced Photon Source at Argonne National Laboratory will be used to capture highly resolved images from multiphase porous medium experiments. In addition to capturing the morphological structure of these systems, pore-scale properties (e.g., pore body/throat distribution and correlation, tortuosity, connectivity, etc ... ) can be calculated from these images. Researchers at the Johns Hopkins University will use the data and results from these experiments to extend their pore-morphological approaches to model imbibition. LB methods will be used to accurately model various aspects of multiphase flow including thick wetting phase films in strongly water-wet systems, heterogeneous wettability, and anisotropic spatial correlations of the pore space.

Hilpert0207719这项合作研究提案旨在将高分辨率层析成像数据集与最先进的孔隙尺度建模技术相结合，以研究非水相液体（NAPL）的流动和截留。 我们将重点关注混合润湿性系统以及几何描述符和各向异性对多相流的影响。 路易斯安那州立大学先进微结构和器件中心的同步加速器显微断层摄影站和阿贡国家实验室的先进光子源将用于从多相多孔介质实验中捕获高分辨率图像。 除了捕获这些系统的形态结构之外，还可以根据这些图像计算孔隙尺度特性（例如，孔体/喉道分布和相关性、弯曲度、连通性等）。 约翰·霍普金斯大学的研究人员将利用这些实验的数据和结果来扩展他们的孔隙形态学方法来模拟自吸。 LB 方法将用于精确模拟多相流的各个方面，包括强水湿系统中的厚润湿相膜、非均匀润湿性和孔隙空间的各向异性空间相关性。
