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.

Surface plot of the volume fraction of liquid, and contour plot of the temperature. In the blue region, the fraction of liquid is close to zero, which illustrates where the liquid is boiling. |
