Boiling Flow
When modeling boiling flows, the mass transfer across the phase boundary, as well as the absorption of latent heat as the liquid evaporates, needs to be accounted for.Here, a liquid is initially at rest above a thin layer of vapor, where the temperature in both phases is that of the saturation temperature. A heat flux is applied at the bottom surface of the domain and, as the vapor-liquid interface heats up, the liquid starts to evaporate causing the position of the interface to change.
