Description
Paper:
S Schlüter, S Berg, M Rücker, RT Armstrong, H-J Vogel, R Hilfer, D Wildenschild: Pore-scale displacement mechanisms as a source of hysteresis for two-phase flow in porous media, Water Resources Research, 52, 2194–2205, doi:10.1002/2015WR018254

Content:
The CT data is provided in a zip folder that contains three subfolders (PD,MI,MD) in which the segmented images for all time steps are stored. In addition, the timestamps and all state variables discussed in the paper (macroscopic pressure difference P_n-P_w, saturation S_w, interfacial area A_wn, Euler characteristic \chi_n; an in addition interface curvature H) are summarized in the Excel file WRR2016_summary_reduced_ROI.xlsx

File Format:
The individual images are stored in the ITK metaimage format. The mhd file contains important meta information and the image is stored as a binary block in the raw file. This file format can be read by any image processing software based on ITK, as well as other common software toolboxes like Fiji/ImageJ, ParaView and QuantIm. If the ITK metaimage file format is not compatible with your software toolbox, then just import the raw file directly according to the meta information stored in the mhd file.

File name convention:
The files are stored according to the following convention:
26_QS_<experiment><sample>_nlm_tv_cor_mrf_fill
experiment: PD= primary drainage, MI= main imbibition, MD=main drainage
sample: from a_A to d_Q

Image content:
Gray values correspond to following material classes:
0 – non-wetting phase
1 – wetting phase
2 – solid phase and exterior
