    • 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 ...

    • A pore network model for calculation of interfacial velocities 

      Nordhaug, Hans Fredrik; Celia, Michael A.; Dahle, Helge K. (Peer reviewed; Journal article, 2003)
      Two-phase flow in porous media is characterized by fluid-fluid interfaces that separate the fluid phases at the pore scale. These interfaces support pressure differences between phases, and their dynamics allow for saturation ...
