[case] SpecificHeatCapacityWithLatentHeat

Model for the apparent specific heat capacity including latent heat \ell

This model is for media with a phase change. This property must be a medium property, it computes the apparent specific heat capacity based on a phase transition spread over a temperature interval:

C_{\mathrm{app}} = \left[C - \varrho_\mathrm{fR} \ell \frac{\partial \phi_\mathrm{f}}{\partial T} \right] \quad\rightarrow\quad c_{\mathrm{app}} = \frac{C_{\mathrm{app}}}{\varrho}

with \ell as specific enthalpy of melting, C as effective volumetric heat capacity and \varrho as the effective density of the mixture, \varrho_\mathrm{fR} as the real density of the frozen phase as well as \phi_\mathrm{f} as the temperature-dependent frozen liquid volume fraction.
