static Scalar Dumux::PengRobinsonMixture< Scalar, StaticParameters >::computeFugacityCoefficient ( const FluidState &  fs,
const Params &  params,
int  phaseIdx,
int  compIdx 
)
inlinestatic

Returns the fugacity coefficient \(\mathrm{[-]}\) of an individual component in the phase.

Parameters
fsThermodynamic state of the fluids
paramsParameters
phaseIdxThe phase index
compIdxThe index of the component

The fugacity coefficient \(\phi_i\) of a component \(i\) is defined as

\[f_i = \phi_i x_i \;,\]

where \(f_i\) is the component's fugacity and \(x_i\) is the component's mole fraction.
