#include <dumux/material/constraintsolvers/computefromreferencephase.hh>

Description

template<class Scalar, class FluidSystem>
class Dumux::ComputeFromReferencePhase< Scalar, FluidSystem >

This makes it is possible to specify just one phase and let the remaining ones be calculated by the constraint solver. This constraint solver assumes thermodynamic equilibrium. It assumes the following quantities to be set:

  • composition (mole+mass fractions) of the reference phase \(x^\kappa_\beta\)
  • temperature of the reference phase \(T_\beta\)
  • saturations of all phases \(S_\alpha\), \(S_\beta\)

  • pressures of all phases \(p_\alpha\), \(p_\beta\)

    \( f^\kappa_\beta = f^\kappa_\alpha = \Phi^\kappa_\alpha(\{x^\lambda_\alpha \}, T_\alpha, p_\alpha) p_\alpha x^\kappa_\alpha\; \),

    \( p_\alpha = p_\beta + p_{c\beta\alpha}\; \),

after calling the solve() method the following quantities are calculated in addition:

  • temperature of all phases \(T_\alpha\), \(T_\beta\)
  • density, molar density, molar volume of all phases \(\rho_\alpha\), \(\rho_\beta\), \(\rho_{mol, \alpha}\), \(\rho_{mol, \beta}\), \(V_{mol, \alpha}\), \(V_{mol, \beta}\)
  • composition in mole and mass fractions and molarities of all phases \(x^\kappa_\alpha\), \(x^\kappa_\beta\), \(X^\kappa_\alpha\), \(X^\kappa_\beta\), \(c^\kappa_\alpha\), \(c^\kappa_\beta\)
  • mean molar masses of all phases \(M_\alpha\), \(M_\beta\)
  • fugacity coefficients of all components in all phases \(\Phi^\kappa_\alpha\), \(\Phi^\kappa_\beta\)
