Calculates the chemical equilibrium from the component fugacities $f^{\kappa }$ in the phase $\alpha$. More...

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 $x_{\alpha }^{\lambda }$ of a phase $\alpha$ as input and calculates the mole fraction of component $\kappa$ in that fluid phase $x_{\alpha }^{\kappa }$. This means that the thermodynamic constraints used by this solver are

$f^{\kappa }={\mathrm{\Phi }}_{\alpha }^{\kappa }(\{x_{\alpha }^{\lambda }\},T_{\alpha },p_{\alpha })p_{\alpha }{x}_{\alpha }^{\kappa }$,

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