Description

template<class TypeTag>
class Dumux::CapillaryDiffusion< TypeTag >

Class for defining the diffusive capillary pressure term of a saturation equation.

Defines the diffusive capillary pressure term of the form

$$\bar \lambda \boldsymbol K \textbf{grad} \, p_c,$$

where $\bar \lambda = \lambda_w f_n = \lambda_n f_w$ and $\lambda$ is a phase mobility and $f$ a phase fractional flow function, $\boldsymbol K$ is the intrinsic permeability and $p_c = p_c(S_w)$ the capillary pressure.
