    • Consistency issues in pdf methods 

      Suciu, Nicolae; Schüler, Lennart; Radu, Adrian Florin; Attinger, Sabine; Vamo̧s, Cǎlin; Knabner, Peter (Tipografia Universitatii Ovidius, 2015)
      Concentrations of chemical species transported in random environments need to be statistically characterized by probability density functions (PDF). Solutions to evolution equations for the one-point one-time PDF are usually ...

    • A convergent mass conservative numerical scheme based on mixed finite elements for two-phase flow in porous media 

      Radu, Florin Adrian; Kumar, Kundan; Nordbotten, Jan Martin; Pop, Sorin Iuliu (2017)
      In this work we present a mass conservative numerical scheme for two-phase flow in porous media. The model for flow consists on two fully coupled, non-linear equations: a degenerate parabolic equation and an elliptic equation. ...

    • Finite volume methods for elasticity with weak symmetry 

      Keilegavlen, Eirik; Nordbotten, Jan Martin (Wiley, 2017-11)
      We introduce a new cell‐centered finite volume discretization for elasticity with weakly enforced symmetry of the stress tensor. The method is motivated by the need for robust discretization methods for deformation and ...

    • Pore-scale investigation of methane hydrate phase transitions and growth rates in synthetic porous media 

      Lysyy, Maksim (The University of Bergen, 2018-06-20)
      A growing demand for energy and natural gas in particular, makes methane gas hydrates a potential target to supplement natural gas production from conventional resources. Several pilot projects have proven the feasibility ...

    • Stable cell-centered finite volume discretization for biot equations 

      Nordbotten, Jan Martin (SIAM, 2016-03-29)
      In this paper we discuss a new discretization for the Biot equations. The discretization treats the coupled system of deformation and flow directly, as opposed to combining discretizations for the two separate subproblems. ...
