Phase Change
When modeling heat transfer in solids, fluids, and porous media, the properties of a phase changing material are specified according to the apparent heat capacity formulation. This formulation gets its name from the fact that the latent heat is included as an additional term in the heat capacity.
The subnode
Phase Change Material
is available under the Solid, Fluid, or Porous Medium node.
With phase transitions in porous media, there is often a remaining phase that does not participate in the phase transition. For example, water in the soil, which does not freeze even at values far lower than 0 degrees, or water in food, which does not evaporate completely during cooking. To consider such residual phases
Immobile Fluids (Porous Medium)
can be used.
