Global weak solutions for a gas liquid model with external forces and general pressure law
Evje, Steinar; Friis, Helmer André (Journal article; Peer reviewed, 2011)In this work we show existence of global weak solutions for a two-phase gas-liquid model where the gas phase is represented by a general isothermal pressure law, whereas the liquid is assumed to be incompressible. To make ... -
Numerical treatment of two-phase flow in capillary heterogeneous porous media by finite-volume approximations
Evje, Steinar; Friis, Helmer André (Journal article; Peer reviewed, 2012)This paper examines two-phase flow in porous media with heterogeneous capillary pressure functions. This problem has received very little attention in the literature, and constitutes a challenge for numerical discretization, ...
