• Contact Angles in Two-Phase Flow Images 

      Hosseinzade Khanamiri, Hamid; Slotte, Per Arne; Berg, Carl Fredrik (Peer reviewed; Journal article, 2020)
      In this work, we calculate contact angles in X-ray tomography images of two-phase flow in order to investigate the wettability. Triangulated surfaces, generated using the images, are smoothed to calculate the contact angles. ...
    • Fluid Topology in Pore Scale Two‐Phase Flow Imaged by Synchrotron X‐ray Microtomography 

      Hosseinzade Khanamiri, Hamid; Torsæter, Ole (Journal article; Peer reviewed, 2018)
      A flow experiment including drainage and imbibition by water and surfactant was performed on a water‐wet Berea sandstone. The three‐dimensional (3‐D) pore scale changes of the fluid configuration were captured under flow ...
    • Geometrically derived efficiency of slow immiscible displacement in porous media 

      Berg, Carl Fredrik; Slotte, Per Arne; Hosseinzade Khanamiri, Hamid (Peer reviewed; Journal article, 2020)
      The efficiency of a displacement is the fraction of applied work over the change in free energy. This displacement efficiency is essential for linking wettability to applied work during displacement processes. We quantify ...
    • Predicting Resistivity and Permeability of Porous Media Using Minkowski Functionals 

      Slotte, Per Arne; Berg, Carl Fredrik; Hosseinzade Khanamiri, Hamid (Journal article; Peer reviewed, 2019)
      Permeability and formation factor are important properties of a porous medium that only depend on pore space geometry, and it has been proposed that these transport properties may be predicted in terms of a set of geometric ...
