Micro-CT Images and Networks
For each image a mhd header (.mhd) file is provided which contain the image information such as size and resolution. To visualise the image you can open the .mhd file in Paraview or Fiji-is-ImageJ. The .mhd also serves as the default input format for our direct flow simulation and network extraction codes.
The Doddington sandstone and Estaillades and Ketton carbonate images were obtained using micro-CT scanning facilities at Imperial College London. The Bentheimer sandstone image is provided by iRock Technologies. The images are segmented using a watershed segmentation algorithm using Avizo image processing software; see Andrew (2004) PhD thesis for the technical details. A summary of the image statistics and single-phase flow properties are presented in Raeini et al (2017). The Bentheimer, Doddington and Estaillades images have been further analysed by Bijeljic et al. (2013) and Alhashmi et al. (2016), for studying transport and chemical reaction.
Velocity and pressure fields for single-phase incompressible flow from the solution of Navier-Stokes equations are available for all of these images. If you want a copy or for any other query, please contact Branko Bijeljic.
