Description

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

Computes the composition of all phases of a N-phase, N-component fluid system assuming that all N phases are present.

The constraint solver assumes the following quantities to be set:

It also assumes that the mole/mass fractions of all phases sum up to 1. After calling the solve() method the following quantities are calculated in addition:

inlinestatic

Computes the composition of all phases of a N-phase, N-component fluid system assuming that all N phases are present.

This function additionally considers a lowering of the saturation vapor pressure of the wetting phase by the Kelvin equation:

\[ p^\textrm{w}_\textrm{sat,Kelvin} = p^\textrm{w}_\textrm{sat} \exp \left( -\frac{p_\textrm{c}}{\varrho_\textrm{w} R_\textrm{w} T} \right) \]

Parameters
fluidStateA container with the current (physical) state of the fluid
paramCacheA container for iterative calculation of fluid composition
knownPhaseIdxThe index of the phase with known properties
