An isenthalpic formulation for simulating geothermal systems with phase changes
Duran Triana, Omar Yesid; Lipovac, Veljko; Keilegavlen, Eirik; Radu, Adrian Florin; Berre, Inga (Chapter; Peer reviewed, 2023)We propose a unified isenthalpic formulation for the equilibrium problem of compositional multiphase mixtures. To solve the equilibrium problem numerically, we used an interior point method with line search and present an ... -
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 ...
