The film boiling of water

Check out this neat animation created in COMSOL multiphysics software that studies the film boiling of water. The "Leidenfrost point" referred to is the lowest temperature at which a hot body submerged in a pool of boiling water is completely blanketed by a vapor film. There is a minimum in the heat flux from the body to the water at this temperature. The animation shows the fluids volume fraction over time as a surface and contour plot. In CFD, volume of fluid (VOF) method is a numerical technique for tracking and locating the free surface (or fluid-fluid interface).
