• Burst Dynamics, Upscaling and Dissipation of Slow Drainage in Porous Media 

      Måløy, Knut Jørgen; Moura, Marcel; Hansen, Alex; Flekkøy, Eirik Grude; Toussaint, Renaud (Peer reviewed; Journal article, 2021)
      We present a theoretical and experimental investigation of drainage in porous media. The study is limited to stabilized fluid fronts at moderate injection rates, but it takes into account capillary, viscous, and gravitational ...
    • Capillary washboarding during slow drainage of a frictional fluid 

      Thorens, Louison; Måløy, Knut Jørgen; Flekkøy, Eirik Grude; Sandnes, Bjørnar; Bourgoin, Mickaël; Santucci, Stephane F A (Peer reviewed; Journal article, 2023)
      Numerous natural and industrial processes involve the mixed displacement of liquids, gases and granular materials through confining structures. However, understanding such three-phase flows remains a formidable challenge, ...
    • Clay alignment in electric fields 

      Castberg, Rene; Rozynek, Zbigniew; Fossum, Jon Otto; Måløy, Knut Jørgen; Dommersnes, Paul; Flekkøy, Eirik Grude (Journal article; Peer reviewed, 2012)
      The response of rotational alignment of lithium fluorohectorite (Li-Fh) to an external electric field has been studied by employing image analysis. Large aggregates consisting of many single clay particles were prepared ...
    • Dynamic Pore Network Study of Immiscible Two-Phase Flow in Porous Media 

      Fyhn, Hursanay (Doctoral theses at NTNU;2023:332, Doctoral thesis, 2023)
      Porous media research has widespread applications in a variety of fields including biology, medicine, and geology. Notably, it can be used to mitigate the effects of climate change through methods of carbon capture and ...
    • Film flow dominated simultaneous flow of two viscous incompressible fluids through a porous medium 

      Aursjø, Olav; Erpelding, Marion; Tallakstad, Ken Tore; Flekkøy, Eirik Grude; Hansen, Alex; Måløy, Knut Jørgen (Journal article; Peer reviewed, 2014-11-19)
      We present an experimental study of two-phase flow in a quasi-two-dimensional porous medium. The two phases, a water-glycerol solution and a commercial food grade rapeseed/canola oil, having an oil to water-glycerol viscosity ...
    • Frictional fluid instabilities shaped by viscous forces 

      Zhang, Dawang; Campbell, James; Eriksen, Jon Alm; Flekkøy, Eirik Grude; Måløy, Knut Jørgen; MacMinn, Christopher W.; Sandnes, Bjørnar (Peer reviewed; Journal article, 2023)
      Multiphase flows involving granular materials are complex and prone to pattern formation caused by competing mechanical and hydrodynamic interactions. Here we study the interplay between granular bulldozing and the stabilising ...
    • Shape of a frictional fluid finger 

      Flekkøy, Eirik Grude; Sandnes, Bjørnar; Måløy, Knut Jørgen (Peer reviewed; Journal article, 2023)
      Frictional fluid dynamics describes the displacement patterns that arise when a confined mixture of liquid and grains are displaced by an immiscible fluid under pressures that are too small to cause drainage into single ...
    • A simplified pore-scale model for slow drainage including film-flow effects 

      Kozlowski Pitombeira Reis, Paula; Moura, Marcel; Linga, Gaute; Rikvold, Per Arne; Toussaint, Renaud; Flekkøy, Eirik Grude; Måløy, Knut Jørgen (Peer reviewed; Journal article, 2023)
      Liquid-filled corners and capillary bridges can establish networks connecting seemingly isolated clusters during drainage in porous media. Coupled with drainage through the bulk of pores and throats, the flow through these ...
    • Stable and unstable capillary fingering in porous media with a gradient in grain size 

      Vincent-Dospital, Tom Yannick Yves; Moura, Marcel; Toussaint, Renaud; Måløy, Knut Jørgen (Peer reviewed; Journal article, 2022)
      Multiphase flows in complex porous networks occur in many natural processes and engineering applications. We present an analytical, experimental and numerical investigation of slow drainage in porous media that exhibit a ...
