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 $\kappa$:

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

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

$$\frac{\partial {\varrho }_g}{\partial t}+\mathrm{\nabla }\cdot (\varrho \mathit{v}-\sum _{\kappa }(D^{\kappa }+D_{\text{t}})\varrho \mathrm{\nabla }{X}^{\kappa })-q=0$$

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.
