Description

For an equations not specific to multiple components see dumux/freeflow/navierstokes/model.hh

The multi-component system is closed by a component mass/mole balance equation for each component \(\kappa\):

\[ \frac{\partial \left(\varrho X^\kappa\right)}{\partial t} + \nabla \cdot \left( \varrho {\boldsymbol{v}} X^\kappa - (D^\kappa + D_\text{t}) \varrho \nabla X^\kappa \right) - q^\kappa = 0 \]

Alternatively, one component balance equation can be replace by a total mass/mole balance equation :

\[ \frac{\partial \varrho_g}{\partial t} + \nabla \cdot \left( \varrho {\boldsymbol{v}} - \sum_\kappa (D^\kappa + D_\text{t}) \varrho \nabla X^\kappa \right) - q = 0 \]

The eddy diffusivity \( D_\text{t} \) is related to the eddy viscosity \( \nu_\text{t} \) by the turbulent Schmidt number, for Navier-Stokes models \( D_\text{t} = 0 \).

\[ D_\text{t} = \frac{\nu_\text{t}}{\mathrm{Sc}_\text{t}} \]

So far, only the staggered grid spatial discretization (for structured grids) is available.
