Hilpert 0207719该合作研究提案旨在将联合收割机高分辨率层析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（NAPLs）的流动和截留。 我们将集中在混合润湿性系统和多相流的几何描述符和各向异性的影响。 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层析成像站和阿贡国家实验室的先进光子源将用于捕获多相多孔介质实验的高分辨率图像。 除了捕获这些系统的形态结构之外，还可以测量孔隙尺度性质（例如，孔隙体/喉道分布和对比、弯曲度、连通性等。可以从这些图像中计算。 约翰霍普金斯大学的研究人员将使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渗吸。 LB方法将被用来准确地模拟多相流的各个方面，包括厚的润湿相膜在强水润湿系统，非均匀润湿性，和各向异性的孔隙空间的空间相关性。

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.
