    • Dimensional reduction of a fractured medium for a two-phase flow 

      Dugstad, Martin Sandanger; Kumar, Kundan (Journal article; Peer reviewed, 2022)
      We consider a porous medium containing a single fracture, and identify the aperture to length ratio as the small parameter ɛ with the fracture permeability and the fracture porosity scaled as exponents of ɛ. We consider a ...

    • Global random walk solvers for fully coupled flow and transport in saturated/unsaturated porous media 

      Suciu, Nicolae; Illiano, Davide; Prechtel, Alexander; Radu, Florin Adrian (Journal article; Peer reviewed, 2021)
      In this article, we present new random walk methods to solve flow and transport problems in saturated/unsaturated porous media, including coupled flow and transport processes in soils, heterogeneous systems modeled through ...

    • Impact of time-dependent wettability alteration on the dynamics of capillary pressure 

      Kassa, Abay; Gasda, Sarah; Kumar, Kundan; Radu, Florin Adrian (Journal article; Peer reviewed, 2020)
      Wettability is a pore-scale property that has an important impact on capillarity, residual trapping, and hysteresis in porous media systems. In many applications, the wettability of the rock surface is assumed to be constant ...

    • Pore-scale dynamics for underground porous media hydrogen storage 

      Lysyy, Maksim; Ersland, Geir; Fernø, Martin (Journal article; Peer reviewed, 2022)
      Underground hydrogen storage (UHS) has been launched as a catalyst to the low-carbon energy transitions. The limited understanding of the subsurface processes is a major obstacle for rapid and widespread UHS implementation. ...

    • Unlocking multimodal PET-MR synergies for geoscience 

      Brattekås, Bergit; Gauteplass, Jarand; Brekke, Njål; Fernø, Martin; Ersland, Geir (Journal article; Peer reviewed, 2020)
      The recent combination of positron emission tomography (PET) and magnetic resonance (MR) imaging modalities in one clinical diagnostic tool represents a scientific advancement with high potential impact in geoscientific ...
