The formulations available for Fick's law related to the reference system.
- Note
- The total flux of a component can be split into an advective and a diffusive part. In our framework, the advective part is based on a momentum balance. Standard momentum balances, e.g., the Navier-Stokes equations or Darcy's law yield mass-averaged velocities (see Multicomponent Mass Transfer, Taylor & Krishna, 1993 [65]), therefore we use the appropriate formulation of Fick's law (mass averaged formulation) per default.
This means that the diffusive fluxes are calculated with the mass fraction gradients and the unit of the fluxes is kg/s. It is also possible to use a molar-averaged reference system, which can be beneficial, e.g., when it is known that the molar-averaged advective velocity would be zero. When using a molar-averaged reference velocity, Fick's law is formulated with mole fraction gradients and the unit of the flux is moles/s. This means that depending on the reference system, the units of the fluxes need to be adapted to be used in mass or mole balances.

Prepares the Riemann problem for the advective flux for the 2D shallow water model. The actual model uses an exact Riemann solver after Torro and the reconstruction after Audusse and a flux limiter for small water depths.
The computed water flux of the Riemann solver is given in m^2/s, the momentum fluxes are given in m^3/s^2. The Riemann flux is multiplied by scvf.area() (given in m for a 2D domain) to get the flux over the face.
- Todo:
- The choice of the Riemann solver should be more flexible
