Description

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

This constraint solver takes the component fugacity \(f^\kappa\) of of component \(\kappa\), the temperature \( T_\alpha \), the pressure \(p_\alpha\) and the composition \(x^\lambda_\alpha\) of a phase \(\alpha\) as input and calculates the mole fraction of component \(\kappa\) in that fluid phase \(x^\kappa_\alpha\). This means that the thermodynamic constraints used by this solver are

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

where \({f^\kappa}\), \( T_\alpha \) and \( p_\alpha \) are fixed values.
