Given a fluid state, return the effective heat conductivity [W/m^2 / (K/m)] of the porous medium.

For two phases, the Somerton law is given by:

\[ \lambda_{pm} = \lambda_{ful,g} + \sqrt{S_w}(\lambda_{ful,w} - \lambda_{vac}) + \sqrt{S_n}(\lambda_{ful,n} - \lambda_{vac}) \]

where $\lambda_{vac}$ is the heat conductivity of the porous medium at vacuum, $\lambda_{ful,\alpha}$ is the heat conductivty of the porous medium if it is fully saturated by phase $\alpha$ and $S_\alpha$ is the saturation of phase $\alpha$.
