Two-scale preconditioning for two-phase nonlinear flows in porous media
Skogestad, Jan Ole; Keilegavlen, Eirik; Nordbotten, Jan Martin (Peer reviewed; Journal article, 2015)Solving realistic problems related to flow in porous media to desired accuracy may be prohibitively expensive with available computing resources. Multiscale effects and nonlinearities in the governing equations are among ... -
Unified flash calculations with isenthalpic and isochoric constraints
Lipovac, Veljko; Duran Triana, Omar Yesid; Keilegavlen, Eirik; Radu, Adrian Florin; Berre, Inga (Journal article; Peer reviewed, 2024)In the unified flash procedure, a persistent set of unknowns and equations are solved in equilibrium calculations, allowing for simultaneous phase stability and split calculations. For fluids in a subcritical thermodynamic ...
