Descriptions

This dataset was used in the study of Van Offenwert et al. (2024). It contains time-resolved laboratory-based micro-CT images of saturated and unsaturated solute injection experiments in sintered glass and Bentheimer sandstone. Based on the grey values in the resolved pore space, pore-scale concentration fields can be quantified. The tracer injection experiments were imaged at 15 s per scan with a voxel size of 13.0 µm (‘Tracer injection experiments’). Each fast imaging experiment was preceded by a higher quality slower pre-scan to determine the static pore structure. All data were acquired with a gantry-based micro-CT system specially designed for in-situ imaging (UGCT). The aim was to analyze pore-scale solute concentration fields to investigate solute spreading and mixing during tracer injection experiments. Further details on the analyses of the micro-CT images can be found in Van Offenwert et al. (2024). The dataset can be used to investigate the influence of pore-scale heterogeneity and the volumetric pump velocity (the Péclet number) on transport processes. The data is provided in 2 subfolders. Detailed information about the files in these subfolders as well as information on how the data is processed is given in the explanatory file ReadMe_Yoda_VanOffenwert.txt.
