• 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 ...
    • 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 ...
    • Rheology of high-capillary number two-phase flow in porous media 

      Sinha, Santanu; Gjennestad, Magnus Aashammer; Vassvik, Morten; Winkler, Mathias; Hansen, Alex; Flekkøy, Eirik Grude (Journal article; Peer reviewed, 2019)
      Flow of immiscible fluids in porous media at high capillary numbers may be characterized by an effective viscosity. We demonstrate that the effective viscosity is well-described by the Lichtenecker-Rother equation. Depending ...
