DARTS-flash

Documentation Status DOI Latest Release pipeline status pypi

DARTS-flash is a standalone library for performing multiphase equilibrium and thermodynamic properties calculations from a range of thermodynamic models. DARTS-flash has interfaces in C++ and Python and it depends on Eigen and Pybind11 libraries.

Features

DARTS-flash has been developed primarily for simulation of flow and transport in CO2-sequestration and geothermal-related subsurface applications. The robustness and accuracy of thermodynamic modelling routines determine the robustness of the compositional simulation.

  • Thermodynamic models
    • Helmholtz-form EoS: Cubic, CPA, IAPWS-95 EoS
    • Activity models for aqueous phase
    • Van der Waals-Platteeuw hydrate EoS
    • Solid phase EoS
  • Stability test and multiphase split
    • Hybrid-EoS implementation
    • Newton methods for second-order convergence
    • Choice of variables, line search procedures, modified Cholesky decomposition
    • (coming soon) (Augmented) free-water flash methods
  • Solution strategies for multiphase equilibrium
    • Two-phase negative flash
    • N-phase stability-flash
    • Multiphase flash at PT/PH/PS state specification
  • C++ interface
    • Partial derivatives for simulation
  • Python interface
    • Phase diagrams
    • EoS property evaluation
    • Gibbs energy and tangent plane analysis
