LhsEval Opm::PengRobinsonMixture< Scalar, StaticParameters >::computeFugacityCoefficient ( const FluidState & fs,

inlinestatic

Returns the fugacity coefficient of an individual component in the phase.

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.
