INSFVMushyPorousFrictionFunctorMaterial
Computes the mushy zone porous resistance for solidification/melting problems.
This material computes the Darcy_coefficient and the Forchheimer_coefficient for a solidification problem. The model uses a mushy-zone approach to compute the friction coefficients.
The coefficients are defined as follows:
where the permeability is defined as follows:
where and are the liquid and solid fraction, the switching function is defined as with and and with and the dendrite spacing is . By default, we set . However, this coefficient may be tuned by the user if experimental data is available.
The Forchheimer coefficient is defined as follows:
where the Ergun coefficient is and is the density of the liquid phase.
commentnote
This material is compatible with PINSFVMomentumFriction for the non standard (simplified) formulation which multiplies the incoming Forchheimer coefficient by the velocity magnitude times velocity component; it is incompatible with the standard Forchheimer formulation which also multiplies with density over two. Thus the user should set the parameter "standard_friction_formulation = false"
