Description

template<class TypeTag>
class Dumux::ScheideggersDispersionTensor< TypeTag >

Scheidegger's dispersion tensor

This class calculates the dispersion tensor for compositional and thermal models using Scheidegger's model. The dispersion tensor is given by:

$D = \frac{v v^{T}}{‖ v ‖} \cdot (α_{L} - α_{T}) + ‖ v ‖ \cdot α_{T} \cdot I$

where $v$ is the velocity vector, $α_{L}$ and $α_{T}$ are the longitudinal and transverse dispersivities, respectively, and $I$ is the identity matrix. The velocity is either taken from the spatial parameters or from the reconstructed velocity field and the dispersivities are taken from the spatial parameters.
